I am using Bootstrap 3 dropdown-menu inside a dynamically generated container. The dropdown-menu appears behind the newly generated elements. See image reference.
container item position: relative; z-index: 1;
dropdown-menu position: absolute; z-index: 10000;
I also did test btn-group with a higher z-index and it did not work.
Here is a working fiddle http://jsfiddle.net/sGem8/
You don't need to add z-index property.. Simply remove it and it will work..
i.e.
#container > li {
display: block;
border-radius: 3px;
position: relative;
padding: 15px;
background: #ecf0f1;
margin-bottom: 15px;
}
Working Fiddle
I have faced the same issue.
Inside the main container which had all the nav-items, I had every outermost div items as position: relative
Only the dropdown menu had position: absolute
To make the dropdown appear above all items, add
.dropdown{
position: absolute;
z-index : 999; //some high value
}
and other items in the container have
.outer-divs{
position: relative;
z-index: 1; //some low value
}
If you still find your dropdown to behave not as expected,
try setting the div item that opens the dropdown when clicked to
.dropdown-container{
position :static;
}
Most people will find the last trick to be the most valuable.
Hope this helps.
Modify the below css in your styles
#container > li {
display: block;
border-radius: 3px;
position: relative;
/* z-index: 0; */
padding: 15px;
background: #ecf0f1;
margin-bottom: 15px;
}

Objective:
I would like the Header, Tab Section, and the Radio Button Section to be fixed in a form (see image below). Meaning that they should always be in view, and never have any overlapping elements.
The form looks like the following:
This is working fine when I simply scroll down on the form:
The Problem:
When I open the Angular Material dropdown, it overlaps over the Radio Button Section:
Here is the HTML. The highlighted sections are the elements that I want to be fixated on the form:
And here is the CSS for the 3 sections
//Header:
.module__header {
position: fixed;
top: 0px;
z-index: 1001;
display: flex;
height: 35px;
width: 100%;
background-color: #082749;
color: #FFFFFF;
font-size: 14px;
font-weight: 500;
align-items: center;
justify-content: stretch;
padding: 0;
margin-bottom: 0;
}
// Tab Section:
.mat-tab-label-container {
position: fixed;
top: 35px;
padding-top: 10px;
z-index: 1001;
width: 100%;
background: #fff;
}
// Radio Button Section:
.timaticFullTextView {
padding-top: 35px;
padding-left: 15px;
padding-bottom: 15px;
background: #fff;
z-index: 1001;
position: fixed;
width: 100%;
border-bottom: 1.5px solid gray;
}
I have tried changing the cdk-overlay-container to a z-index of <1001, but that still is overlapping the Radio Button Section.
How can I have the opened dropdown display underneath all 3 sections?
Edit: Adding screenshot to show the cdk-overlay that is giving issues. I have tried removing and lowering the z-index, but it doesn't have any effect
The problem is that mat-tab-body has z-index: 1 and this won't allow your fixed view inside to have a higher elevation. You can remove the z-index from mat-tab-body put then your content without a z-index won't be clickable anymore so you have to add a z-index and position to your not fixed content.
The code would have to look something like this:
<mat-tab>
<mat-tab-body> <!-- <-- added automatically -->
<div class="tab-header"></div>
<div class="tab-content"></div>
</mat-tab-body>
</mat-tab>
::ng-deep mat-tab-body {
z-index: unset !important;
}
.tab-header {
position: fixed;
z-index: 1001;
}
.tab-content {
position: relative;
z-index: 1;
}
You've found the right element whilst applying styles to the wrong one.
Here is how I made it work
.cdk-global-overlay-wrapper, .cdk-overlay-container {
z-index: 99999 !important;
}
I'm coding an image overlay w/ jQuery, and I got it working (somewhat). If you hover over the first image, it successfully appears; however, if you hover over the second one, it doesn't even work. I don't even know what the problem is! I think it has to do with unique IDs or whatever. I tried classes, and it didn't work.
Here is the fiddle :: http://jsfiddle.net/PFWcz/7/
$(document).ready(function () {
$('.overlay-link').mouseover(function () {
$(this).find('.overlay').fadeIn(200);
}).mouseleave(function () {
$(this).find('.overlay').fadeOut(200);
});
});
There are a few issues. As esqew pointed out, you're using the same IDs, which must be unique.
Addressing that, you'll still see the "same" overlay in your fiddle (http://jsfiddle.net/PFWcz/7/), but it's actually not - you're just now seeing a positioning issue.
Take a look at this fiddle:
http://jsfiddle.net/PFWcz/10/
You'll notice that when you hover over the first image, the red overlay is "1", and when you hover over the second image, the overlay is "2".
Previously (with the "helloooooo" text), the red overlays appeared the same (because of the content and positioning)...
Address the ID and position issues, and it should work.
Here's a fiddle demonstrating fixed position and ID:
http://jsfiddle.net/PFWcz/16/
The main changes is giving the container (<div>) positioning:
div {
float: left;
margin: 30px;
position: relative;
}
Also, I removed offsets (left, top) and floats, applying those to the parent container. A quick, simple fix.
You need to make your overlay-link elements your containers from which child elements inherit positions.
<a class="overlay-link">
<img src="https://d13yacurqjgara.cloudfront.net/users/67256/screenshots/1191507/shooot.png"/>
<span class="overlay"><i>hellllllllooooooo</i></span>
</a>
Your overlay-link class needs to have position: relative and will define the position and size of it and its children:
.overlay-link {
position: relative;
display: block;
width: 292px;
height: 219px;
margin: 30px;
}
Any child inside needs to have position: absolute and its width and height set to 100% of the container:
img {
position: absolute;
border-radius: 2px;
width: 100%;
height: 100%;
top: 0;
left: 0;
}
.overlay {
background-color: rgba(223, 71, 71,0.70);
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
border-radius: 2px;
display: none;
text-align:center;
}
Now when you hover over an element, it will create the overlay over that element and not the other one as you were experiencing earlier.
Jsfiddle: http://jsfiddle.net/PFWcz/14/
You're using the same id, which must be unique. Use the class attribute.
As some of the answered already said there is issue with the id's, I don't want to repeat. Since you have a multiple place where you want to show some text on rollover, using class would be a better solution/way to go ahead with.
Here is the change I did in the fiddle:
.overlay-link { /*This class is added. Since an absolute positioned element places itself relative to its parent who is either a relative positioned element or an absolute positioned element. I made the parent of the .overlay div relative.*/
position: relative;
background-color: #ff0;
}
.overlay {
position: absolute;
background-color: rgba(223, 71, 71,0.70);
left: -322px; /*Positioning the .overlay element based on its parents left*/
width: 292px;
height: 219px;
border-radius: 2px;
top: 30px;
display: none;
text-align:center;
}
.overlay i { /*There is no .shot element in the DOM. I replaced it by .overlay*/
background-color: #df4747;
border-radius: 999px;
padding: 10px;
width: 60px;
height: 60px;
color: #fff;
font-size: 30px;
top: 80px;
left: 116px;
position: absolute;
display: block;
}
This is based on my understanding. Let me know if it works.
Here, this is what you want
Fiddle: http://jsfiddle.net/D33Yk/
$(window).on('load',function () {
$('.overlay-link').mouseover(function(){
var overlay = $(this).children('.overlay');
var img = $(this).children('img');
$(overlay).css('left',$(img).offset().left);
$(overlay).css('top',$(img).offset().top);
$(overlay).css('width',$(img).width());
$(overlay).css('height',$(img).height());
$(overlay).fadeIn(200);
}).mouseleave(function(){
$(this).children('.overlay').fadeOut(200);
});
});
Because you had the overlay positioned absolutely in CSS, both overlays always covered the first image. I now set the left, top, width and height in JS, so the overlays cover their respective image.
I also changed this in CSS:
.overlay {
display: none;
position: absolute;
background-color: rgba(223, 71, 71,0.70);
border-radius: 2px;
text-align:center;
}
removed the top, left, width, height
...and this in HTML (I changed both, but I only show one since they are identical):
<div>
<a class="overlay-link">
<img src="https://d13yacurqjgara.cloudfront.net/users/67256/screenshots/1191507/shooot.png"/>
<span class="overlay"><i>hellllllllooooooo</i></span>
</a>
</div>
changed all the id's to classes, and removed id where it was not necessary
I'm using superfish menu for the WordPress. I want to add some margin between the menu parent item and its dropdown and want to add an icon on the top of the drop down, so that it looks like following image:
The menu markup is automatically generated by the WordPress so it cannot be changed. I'm trying following CSS but it does not seem to work:
ul > li ul.subs{
margin-top: 10px;
}
ul > li ul.subs:before{
content: " ";
display: block;
height: 10px;
width: 20px;
position: absolute;
top: 0;
background: url('http://i.imgur.com/NL4Rq2S.png') no-repeat center bottom;
}
Problems:
When I hover, the sub menu disappears
The arrow icon does not appear.
Demo:
http://jsfiddle.net/y9Rk9/
The solution for the problem 2 is change the :before position to relative
The solution for the problem 1 is to make the menu height higher
ul > li ul.subs{
padding-top: 10px;
}
ul > li ul.subs::before{
content: " ";
display: block;
height: 10px;
width: 20px;
position: relative;
top: 0;
background: url('http://i.imgur.com/NL4Rq2S.png') no-repeat center bottom;
}
http://jsfiddle.net/y9Rk9/11/
Use ul > li ul.subs {padding-top: 10px;} instead margin-top: 10px;

How would I place the page content of the following example - http://jsfiddle.net/cq8dC/ to the right side of the nav sidebar, rather than behind it?
Update the style. Add style padding-left: 255px; to .horizontal
.horizontal
{
display: inline-block;
padding-left: 255px;
vertical-align: top;
white-space: normal;
width: 100%;
}

First, you should add a container to your content. I've called it #Content.
Then I've added these stylings to the CSS:
body {
overflow: hidden;
}
#Content {
left: 240px;
right: 0;
top: 0;
bottom: 0;
position: fixed;
overflow: scroll;
}
This makes the #Content take the resting place in the page and be scrollable on its own.
Also I've updated the JavaScript
The root is now the #Content element and I'm using position() instead of offset(). I'm doing this because position() Get the current coordinates of the first element in the set of matched elements, relative to the offset parent (from the documentation).
I am trying to hide jQuery-ui dialog's title bar but keep the close button in the title bar visible. I have searched lots of post on stackoverflow like this one. In each post the title bar is hidden but the space taken by the bar is still there. I want to remove that space also but without removing the close button.
How can i do this?
Based on this answer:
Use .dialog("widget") option to locate the div wrapper for the dialog. The wrapper contains all the markup used for the dialog including header, title bar and close button; and the dialog content itself. Here is one way to invoke the method and hide the title bar:
$("#id").dialog({
autoOpen: false
}).dialog("widget").find(".ui-dialog-title").hide();
You can then use CSS to eliminate unnecessary margin, border and padding. For example:
.ui-dialog-titlebar {
float: right;
border: 0;
padding: 0;
}
.ui-dialog-titlebar-close {
top: 0;
right: 0;
margin: 0;
z-index: 999;
}
Here is a demo based on above code plus it adds the necessary styles using jQuery.
If you want to remove the titelbar and keep the close icon using styles only, use the styles below. It shrinks the title bar to the size of the close icon and hides it behind. ui-icons_6e6e6e_256x240.png i created by lightening the ui-icons_222222_256x240.png image that jqueryui comes with.
.ui-dialog .ui-dialog-titlebar.ui-widget-header{background: none; border: none; height: 20px; width: 20px; padding: 0px; position: static; float: right; margin: 0px 2px 0px 0px;}
.ui-dialog-titlebar.ui-widget-header .ui-dialog-title{display: none;}
.ui-dialog-titlebar.ui-widget-header .ui-button{background: none; border: 1px solid #CCCCCC;}
.ui-dialog .ui-dialog-titlebar .ui-dialog-titlebar-close{margin: 0px; position: static;}
.ui-dialog .dialog.ui-dialog-content{padding: 0px 10px 10px 10px;}
.ui-dialog .ui-dialog-titlebar .ui-dialog-titlebar-close .ui-icon{position: relative; margin-top: 0px; margin-left: 0px; top: 0px; left: 0px;}
.ui-dialog .ui-dialog-titlebar .ui-state-default .ui-icon {background-image: url("/css/ui-lightness/images/ui-icons_6e6e6e_256x240.png");}
.ui-dialog .ui-dialog-titlebar .ui-state-hover .ui-icon {background-image: url("/css/ui-lightness/images/ui-icons_222222_256x240.png");}
The way I see it, you have 3 options.
Yes, eliminate the titlebar completely and add a custom one that you can style to match the default one, using absolute positioning should be the key.
If you have the time, extend (not overwrite) the _create method of the dialog https://github.com/jquery/jquery-ui/blob/master/ui/jquery.ui.dialog.js#L74 to do what you need
Work with CSS hackery to keep the titlebar there with a height of 0 for all elements but the close button.
Either one has their cons and pros, I would recommend #2 the best if you can, here's some info on how to work with widgets http://api.jqueryui.com/jQuery.widget/
This is How it can be done.
Go to themes folder--> base--> open jquery.ui.dialog.css
Find
Followings
if you don't want to display titleBar then simply set display:none as i did in the following.
.ui dialog.ui-dialog .ui-dialog-titlebar
{
padding: .4em 1em;
position: relative;
display:none;
}
Samilarly for title as well.
.ui-dialog .ui-dialog-title {
float: left;
margin: .1em 0;
white-space: nowrap;
width: 90%;
overflow: hidden;
text-overflow: ellipsis;
display:none;
}
Now comes close button you can also set it none or you can set its
.ui-dialog .ui-dialog-titlebar-close {
position: absolute;
right: .3em;
top: 50%;
width: 21px;
margin: -10px 0 0 0;
padding: 1px;
height: 20px;
display:none;
}
I did lots of search but nothing then i got this idea in my mind. However this will effect entire application to don't have close button,title bar for dialog but you can overcome this as well by using jquery and adding and setting css via jquery
here is syntax for this
$(".specificclass").css({display:normal})
