How to always show submenu in vertical menu with this js file?

My question is if anybody knows what to change in the following js file to always show submenu on the vertical menu , meaning to show the submenu on page load and stay shown whether i hover on it or not, in clear make it part of the vertical menu and not an hidden sub menu that you have to hover on the parent category to access.
What do i need to change in the following code to acomplish that, :

UPDATE:
So i managed to do it by diabling all the code (with /*) related to hover effect from the line "// HoverIntent Configuration" to "// menu slide hoverIntend" and by twicking the css a bit for presentation , seemed to do the trick to always showing submenus but for those who are interested i also found a way by adding to the css the line "height:auto", that also seemed to work fairly nicely.
Anyway thanks guys for yor answers anyway , it's always nice to to know that we have a place you can turn to when we are stuck !

trying to stop textarea from growing after 300px and then destroying autogrow textarea

I am Trying to stop a textarea with autogrow.js from growing after 300px height and then destroying autogrow textarea so that it has scrollbars, although the code I have used to do this is working fine I can stop the textarea from growing after 300px but when that happens the textarea becomes smaller than 300px suddenly.
I need it to stop growing at 300px but still remain 300px in height, is this possible?
I am recreating the facebook messages box - the text area can grow but after a certain height it stops growing and the textarea has scrollbars and once you delete text from the textarea the scrollbars go away and the textarea can then grow again.
I have a working jsfiddle example with my problem inside it.
http://jsfiddle.net/jphillips/k2a2pwc8/2/
here is the code also
function scrollar() {
elem = document.getElementById('box_area');
if (elem.clientHeight < elem.scrollHeight) {
alert('has scrollbars');
var inpbh = $("#inner_postbox").height();
var inpbh_val = $("#box_area_height").val(inpbh);
$("#box_area").height(inpbh_val);
//$("#box_area").autosize();
if ($("#box_area").hasClass("detract")) {
var inpbh = $("#inner_postbox").height();
var inpbh_val = $("#box_area_height").val(inpbh);
$("#box_area").height(inpbh_val);
}
} else {
$("#box_area").autosize();
$("#box_area").attr('class', 'expand');
}
}
$("#box_area").autosize();
$("#box_area").keyup(function() {
if ($("#box_area").height() > 300) {
if ($("#box_area").hasClass("expand")) {
$("#box_area").trigger('autosize.destroy');
$("#box_area").attr('class', 'detract');
}
} else {
$("#box_area").autogrow();
$("#box_area").attr('class', 'expand');
}
});

$("#box_area").addClass('expanded');
just add this piece of code to the keyup function
$("#box_area").keyup(function() {
if ($("#box_area").height() > 300) {
if ($("#box_area").hasClass("expand")) {
$("#box_area").trigger('autosize.destroy');
$("#box_area").attr('class', 'detract');

}
} else {
$("#box_area").autogrow();
$("#box_area").attr('class', 'expand');

Jquery Help Need For Div Height

i'm trying to get the auto height of my div, normally the div box its setup via css 160px but with overflow: hidden; how i can check the auto height its more then 160px or not via jquery ?
i need this because i have box what i have a button for Show More or Show Less so if the height its not bigger then normally height 160px to pass the command ... right now its making my box smaller
My code is this:
<script type="text/javascript">
$("#Show_More_Websites").click(function() {
var Button_Value = $("#Show_More_Websites").attr("value");
var Box_Height = $('.Box_Show_Websites').outerHeight();
if(Button_Value == "Show More") {
if(Box_Height <= "160") {
var el = $('.Box_Show_Websites'),
curHeight = el.height(),
autoHeight = el.css('height', 'auto').height();
el.height(curHeight).animate({height: autoHeight}, 500);
}
$("#Show_More_Websites").attr('value', 'Show Less');
}
if(Button_Value == "Show Less") {
var el = $('.Box_Show_Websites'),
curHeight = el.height(),
autoHeight = el.css('height', '160px').height();
el.height(curHeight).animate({height: autoHeight}, 500);
$("#Show_More_Websites").attr('value', 'Show More');
}
});
</script>
Update
Here you can find my code: http://jsfiddle.net/rAjBH/

here is the solution
demo fiddles - Note: the following fiddle has change in only html part to increase the autoheight using html <br/>
http://jsfiddle.net/rAjBH/1/ - autoHeight is less
http://jsfiddle.net/rAjBH/2/ - auto height is more
$(document).ready(function() {
$("#Show_More_Websites").click(function() {
var Button_Value = $("#Show_More_Websites").attr("value");
var el = $('.Box_Show_Websites')
var Box_Height = el.outerHeight();
var autoHeight = el.css('height', 'auto').height();
el.css('height',Box_Height+'px');
if(Button_Value == "Show More") {
if(autoHeight > Box_Height) {
el.height(curHeight).animate({height: autoHeight}, 500);
}
$("#Show_More_Websites").attr('value', 'Show Less');
}
if(Button_Value == "Show Less") {
curHeight = el.height();
autoHeight = el.css('height', '160px').height();
el.height(curHeight).animate({height: autoHeight}, 500);
$("#Show_More_Websites").attr('value', 'Show More');
}
});
});

jQuery Set Height of Element to Highest in the group

I'm trying to work with jQuery to find the highest element from the first 3 elements within a div then set all 3 the same height then check the next 3 and set them.. etc.. if my window width == X, also if the window width is < X then find the highest 2 elements then set them, then the next 2 then the next 2 etc.
This is my current code which works for all the elements, I would just like to to go through the elements in groups (2's and 3's) and set the height for that group based on the result and window size.
// Find highest element and set all the elements to this height.
$(document).ready(function () {
// Set options
var height = 0;
var element_search = "#cat_product_list #cat_list";
var element_set = "#cat_product_list #cat_list";
// Search through the elements set and see which is the highest.
$(element_search).each(function () {
if (height < $(this).height()) height = $(this).height();
//debug_(height,1);
});
// Set the height for the element(s if more than one).
$(element_set).each(function () {
$(element_set).css("height", (height+40) + "px");
});
});
Any help is much appreciated :)

Try this for setting all of them to the max height:
$(document).ready(function() {
var maxHeight = 0;
$("#cat_product_list #cat_list").each(function() {
if ($(this).outerHeight() > maxHeight) {
maxHeight = $(this).outerHeight();
}
}).height(maxHeight);
});
Update 22/09/16: You can also achieve the same thing without any Javascript, using CSS Flexbox. Setting the container element to have display: flex will automatically set the heights of the elements to be the same (following the highest one).

I've sorted this now,
Check out my Fiddle:
http://jsfiddle.net/rhope/zCdnV/
// Find highest element and set all the elements to this height.
$(document).ready(function () {
// If you windows width is less than this then do the following
var windowWidth = $(window).width();
if (windowWidth < 2000) {
var i = 0,
quotes = $("div#cat_product_list").children(),
group;
while ((group = quotes.slice(i, i += 2)).length) {
group.wrapAll('<div class="productWrap"></div>');
}
}
// Find the width of the window
var windowwidth = $(window).width();
//debug_(windowwidth);
// Set options
var height = 0;
var element_wrap = ".productWrap";
var element_search = ".cat_list";
// Search through the elements set and see which is the highest.
$(element_wrap).each(function () {
$(this).find(element_search).each(function () {
if (height < $(this).height()) height = $(this).height();
});
//alert("Block Height: " +height);
// Set the height for the element wrap.
$(this).css("height", (height) + "px");
// Unset height
height = 0;
});
});

Just to add another suggestion. Here is a jQuery plugin I wrote that accepts one parameter. You can call it like this:
$('.elementsToMatch').matchDimensions("height");
You can match the height, width or if no parameter is entered, both dimensions.
$(function() {
$(".matchMyHeight").matchDimensions("height");
});
(function($) {
$.fn.matchDimensions = function(dimension) {
var itemsToMatch = $(this),
maxHeight = 0,
maxWidth = 0;
if (itemsToMatch.length > 0) {
switch (dimension) {
case "height":
itemsToMatch.css("height", "auto").each(function() {
maxHeight = Math.max(maxHeight, $(this).height());
}).height(maxHeight);
break;
case "width":
itemsToMatch.css("width", "auto").each(function() {
maxWidth = Math.max(maxWidth, $(this).width());
}).width(maxWidth);
break;
default:
itemsToMatch.each(function() {
var thisItem = $(this);
maxHeight = Math.max(maxHeight, thisItem.height());
maxWidth = Math.max(maxWidth, thisItem.width());
});
itemsToMatch
.css({
"width": "auto",
"height": "auto"
})
.height(maxHeight)
.width(maxWidth);
break;
}
}
return itemsToMatch;
};
})(jQuery);
.matchMyHeight {background: #eee; float: left; width: 30%; margin-left: 1%; padding: 1%; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="matchMyHeight">
Div 1
</div>
<div class="matchMyHeight">
Div 2
</div>
<div class="matchMyHeight">
Div 6<br> Div 6<br> Div 6<br> Div 6
</div>

var highHeight = "0";
$(".item").each(function(){
var thHeight = $(this).height();
if(highHeight < thHeight ){
highHeight = thHeight;
}
});
console.log(highHeight)

jQuery Image Viewport Calculation Algorithm to Avoid Scrollbars

I am creating an image hover effect but I am having problem with it. When I hover over certain images, the scrollbars appear which I want to avoid but don't know how to do so. I believe it has to do with viewport and calculations but am not sure how that is done.
Example Here
JSBin Code
Here is the code:
$('.simplehover').each(function(){
var $this = $(this);
var isrc = $this[0].src, dv = null;
$this.mouseenter(function(e){
dv = $('<div />')
.attr('class', '__shidivbox__')
.css({
display: 'none',
zIndex : 9999,
position: 'absolute',
top: e.pageY + 20,
left: e.pageX + 20
})
.html('<img alt="" src="' + isrc + '" />')
.appendTo(document.body);
dv.fadeIn('fast');
})
.mouseleave(function(){
dv.fadeOut('fast');
});
});
Can anyone please help me how do I make it so that hovered image appears at such place that scrollbars dont appear? (Of course we can't avoid scrollbar if image size is very very big)
I just want to show original image on zoom while avoiding scrollbars as much as possible.
Please note that I am planning to convert it into jQuery plugin and therefore I can't force users of plugin to have overflow set to hidden. The solution has do with viewport, left, top, scroll width and height, window width/height properties that I can incorporate into plugin later on.
Update:
I have come up with this:
http://jsbin.com/upuref/14
However, it is very very hacky and not 100% perfect. I am looking for a better algorithim/solution. I have seen many hover plugins that do this very nicely but since I am not that good at this, I can't do it perfectly well. For example Hover Zoom Chrome Plugin does great job of showing hovered images at appropriate place based on their size.

Like this:
html{overflow-x:hidden;}
html{overflow-y:hidden;}
All you need to do is add these definitions to your CSS and you're done.
Update with Resize: this is the mouseenter code for resizing and repositioning the pictures BOTH horizontally and vertically. Now, no matter where the HOVER image shows up, it's resized and positioned to always show in full AND uncut. As far as the scrollbars are concerned, if you show more thumbnails than can fit on the page, you will have scrollbars even before the HOVER images show up.
FINAL AND WORKING UPDATE: Because you had focused on the scrollbars being hidden, I think you overlooked the fact that if you put more thumbnails than the viewport can contain, the scrollbars would show up anyway and that therefore, since the user can scroll down the document, when you calculate the position of the hover image, not only do you need to account for the resize but you also to account for the scrollTop position too! FINAL JSBIN HERE, all pictures are showing RESIZED and in FULL no matter where the scrollTop is and no matter what the viewport size is.
$this.mouseenter(function () {
dv = $('<div />')
.attr('class', '__shidivbox__')
.css({
'display': 'none',
'z-index': 9999,
'position': 'absolute',
'box-shadow': '0 0 1em #000',
'border-radius': '5px'
})
.html('<img alt="" src="' + isrc + '" />')
.appendTo(document.body);
var DocuWidth = window.innerWidth;
var DocuHeight = window.innerHeight;
var DvImg = dv.find('img');
var TheImage = new Image();
TheImage.src = DvImg.attr("src");
var DivWidth = TheImage.width;
var DivHeight = TheImage.height;
if (DivWidth > DocuWidth) {
var WidthFactor = (DivWidth / DocuWidth) + 0.05;
DivHeight = parseInt((DivHeight / WidthFactor), 10);
DivWidth = parseInt((DivWidth / WidthFactor), 10);
}
var ThumbHeight = $this.height();
var ThumbWidth = $this.width();
var ThumbTop = $this.position().top;
var ThumbLeft = $this.position().left;
var SpaceAboveThumb = ThumbTop - $(document).scrollTop();
var SpaceBelowThumb = DocuHeight - ThumbTop - ThumbHeight + $(document).scrollTop();
var MaxHeight = Math.max(SpaceAboveThumb, SpaceBelowThumb);
if (DivHeight > MaxHeight) {
var HeightFactor = (DivHeight / MaxHeight) + 0.05;
DivHeight = parseInt((DivHeight / HeightFactor), 10);
DivWidth = parseInt((DivWidth / HeightFactor), 10);
}
var HoverImgLeft = 0;
var HoverImgTop = 0;
if (SpaceBelowThumb > SpaceAboveThumb) {
HoverImgTop = ThumbTop + ThumbHeight;
} else {
HoverImgTop = ThumbTop - DivHeight;
}
HoverImgTop = (HoverImgTop < 0) ? 0 : HoverImgTop;
HoverImgLeft = (DocuWidth - DivWidth) / 2;
dv.find('img').css({
'width': DivWidth,
'height': DivHeight,
'border-radius': '5px'
});
dv.css({
'left': HoverImgLeft,
'top': HoverImgTop
});
dv.fadeIn('fast');
});

Well, this looks fun. Anyway, here's my answer. I've been watching this for a few days and though I'd chip in too. The following will make sure that the hovering images do not go out of the viewport and in the event that the width of the image is bigger than the available space for display, the display of the image will be resized (You can comment out the code that does this if you don't want it. Just look for the word "resize" in the code).
var $document = $(document);
$('.simplehover').each(function(){
var $this = $(this);
// make sure that element is really an image
if (! $this.is('img')) return false;
var isrc = $this[0].src, ibox = null;
if (! isrc) return false;
ibox = $('<img />')
.attr('class', 'simpleimagehover__shidivbox__')
.css({
display: 'none',
zIndex : 99,
MozBoxShadow: '0 0 1em #000',
WebkitBoxShadow: '0 0 1em #000',
boxShadow: '0 0 1em #000',
position: 'absolute',
MozBorderRadius : '10px',
WebkitBorderRadius : '10px',
borderRadius : '10px'
})
.attr('src', isrc)
.appendTo(document.body);
$this.bind('mouseenter mousemove', function(e) {
$('.simpleimagehover__shidivbox__').hide();
var left = e.pageX + 5,
top = e.pageY + 5,
ww = window.innerWidth,
wh = window.innerHeight,
w = ibox.width(),
h = ibox.height(),
overflowedW = 0,
overflowedH = 0;
// calucation to show element avoiding scrollbars as much as possible - not a great method though
if ((left + w + $document.scrollLeft()) > ww)
{
overflowedW = ww - (left + w + $document.scrollLeft());
if (overflowedW < 0)
{
left -= Math.abs(overflowedW);
}
}
// 25 is just a constant I picked arbitrarily to compensate pre-existing scrollbar if the page itself is too long
left -= 25;
left = left < $document.scrollLeft() ? $document.scrollLeft() : left;
// if it's still overflowing because of the size, resize it
if (left + w > ww)
{
overflowedW = left + w - ww;
ibox.width(w - overflowedW - 25);
}
if (top + h > wh + $document.scrollTop())
{
overflowedH = top + h - wh - $document.scrollTop();
if (overflowedH > 0)
{
top -= overflowedH;
}
}
top = top < $document.scrollTop() ? $document.scrollTop() : top;
ibox.css({
top: top,
left: left
});
ibox.show();
});
$('.simpleimagehover__shidivbox__').mouseleave(function(){
$('.simpleimagehover__shidivbox__').hide();
});
$document.click(function(e){
$('.simpleimagehover__shidivbox__').hide();
});
$document.mousemove(function(e){
if (e.target.nodeName.toLowerCase() === 'img') {
return false;
}
$('.simpleimagehover__shidivbox__').hide();
});
});
While my solution itself is not perfect, you might find something useful in there that can help you determine the viewport. Also, you might want to think about the performance of the code. Since this is a plugin that you're building, you'll want to make some optimizations before releasing it to public. Basically, just make sure it's not slow.

You can position the image based on the available width: http://jsbin.com/upuref/19/
This demo takes in account the available space for positioning the image (i.e. the window width minus the image width). Also I've improved the event order, with the popup div only starting its fade-in after the image has been loaded.

My answer too (JSBin DEMO)
$('.simplehover').each(function(){
var $this = $(this);
// make sure that element is really an image
if (! $this.is('img')) return false;
var isrc = $this[0].src, dv = null;
if (! isrc) return false;
$this.mouseenter(function(e){
// mouse x position
var initXPos = e.pageX;
var initYPos = e.pageY+20-$(window).scrollTop();
var windowWidth = $(window).width();
var windowHeight = $(window).height();
// load original image
var $img = $('<img/>');
$img.on('load',function(eload) {
var widthImage = this.width;
var heightImage = this.height;
// set inline style for get sizes after (see problems webkit and cache)
$(this).css('width',widthImage);
$(this).css('height',heightImage);
var ratio = widthImage/heightImage;
var finalXPos = initXPos+widthImage>windowWidth? windowWidth-widthImage-5 : initXPos;
var finalYPos = initYPos;
var img = this;
// resize image if is bigger than window
if(finalXPos<0) {
finalXPos = 0;
$img.css('width', windowWidth-10);
$img.css('height',(windowWidth-10)/ratio);
}
// If overflow Y
if(finalYPos+getSize($img,'height')>windowHeight) {

this script adapt the image to window size and adjust x position if needed.
