I have an accordion to hide blog posts in a webpage. I have a downwards arrow which I want to rotate to an upwards arrow when a blog post (accordion section) has been opened. These should be independent of other arrows attached to other posts obviously.
I am using bootstrap framework as a base. I tried following the instructions here http://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_ref_js_collapse_togglebtn&stacked=h , along with what I already know/have used to try to add rotation. My problem is that, as I'm not using a button (the whole blog post is clickable to expand and collapse it), I can't work out what I need to put in the javascript where the question marks are.
(adding a data-target attribute to the tag breaks the expandability of the post).
$(" ??? ").on("hide.bs.collapse", function(){
$('.expand-image.text-center.glyphicon.glyphicon-chevron-down').addClass('turn-arrow');
});
$(" ??? ").on("show.bs.collapse", function(){
$('.expand-image.text-center.glyphicon.glyphicon-chevron-down').removeClass('turn-arrow');
});
expand-image.text-center.glyphicon.glyphicon-chevron-down.turn-arrow {
-webkit-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
transform: rotate(-90deg);
}

You can attach the eventHandler on any Element, that is one of the parent Elements of .collapse. This is because the Event is triggered on the .collapse Element and bubbles all the way uppward. You can read more about event bubbling here.
You could, for example, attach the eventHandler to every Element with class "blog" as I did to solve your problem.
Relevant jsFiddle
$(".blog").each(function () {
$(this).on("hide.bs.collapse", function () {
$(this).find('.expand-image.text-center.glyphicon.glyphicon-chevron-down').removeClass('turn-arrow');
});
$(this).on("show.bs.collapse", function () {
$(this).find('.expand-image.text-center.glyphicon.glyphicon-chevron-down').addClass('turn-arrow');
});
});
Note the .each at the beginning. This attaches a different eventHandler to every Element matching the selector.
Now you can search the icon to be rotated in this Element --> $(this).find(
This will only find the one arrow inside the clicked blog element.
A very detailed explanation can also be found in this post.

So firstly I will admit I am a kook and have no understanding of javascript, I've jumped onto w3schools and tried to learn how to adjust the following however I have failed miserably. I understand that the solution to this question will not benifit the masses but it will sure help me, grateful for any advise.
The following script will animate the first panel-heading in an accordion list to the top of the webpage. I am however nesting many accordions inside one another (can see example here) so as you click deeper into the hierarchy the html will animate and the open accordion will be off screen at the bottom.
I need to specify the panel-heading of the opening panel-title and have that animate to the top instead of the previous or parent like what is happening now.
So I believe I need to change prev('.panel-heading'); into current panel-heading somehow??
The script
$(".panel-group").on("shown.bs.collapse", function () {
var myEl = $(this).find('.collapse').prev('.panel-heading');
$('html, body').animate({
scrollTop: $(myEl).offset().top
}, 500);
});
<!-- ACCORDION-->
<div id="accordion" class="panel-group">
<div class="panel panel-default">
<div id="heading" class="panel-heading">
<h4 class="panel-title"><a data-toggle="collapse" data-parent="#accordion" href="#collapse1" aria-expanded="false">Panel Title 1</a></h4>

I tried to incorporate solutions from experts all over but I still cannot get my columns to open when I hover the mouse over the panel.
What I'd like to achieve is:
When the mouse is moved to any panel area (it does not have to be over the actual anchor text), the panel body automatically opens (and subsequently all other panels close which the code already does).
When the mouse leaves the panel area the panel body automatically collapses.
Please review my code and let me know what I am doing wrong. Thank you very much for your time!

In jscript
$(".panel-heading").mouseenter(function () {
$(".panel-collapse").fadeIn();
});
$(".panel-collapse").mouseleave(function(){
$(".panel-collapse").fadeOut();
});
Oh, I did this
.panel-title > a {
width: 100%;
display: block;
}
and the whole panel is clickable... but it still requires a click.
I am not 100% sure of what class to give the one you don't want to collapse (e.g expanded?) But this should remove the 'collapsed' class from the only the one that raised the event:
$(".panel-heading").mouseenter(function () {
$(this).click();
});
$(".panel-collapse").mouseleave(function(){
$(this).click();
});
Hope this will work for you.

I have two of these on my page that want them to collapse or expand independent of each other , I do not want one of them to have affect on status of other ones.
So I have something like this:
<div class="container">
<div class="panel-group" id="accordion">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#PANEL1">
<span class="glyphicon glyphicon-chevron-down"></span>
PANEL 1
</a>
</h4>
</div>
<div id="PANEL1" class="panel-collapse collapse in">
<div>
THERE IS A FORM HERE THAT IS THE STUFF IN THIS PANEL
</div>
</div>
</div>
</div>
</div>
and then one more under it, very similar copy paste, just the ID of inner DIV is different:

<div id="PANEL2" class="panel-collapse collapse in">
<div>
THERE IS another FORM HERE THAT IS THE STUFF IN THIS PANEL
</div>
</div>
</div>
</div>
</div>
and then my JavaScript that is this:
$('.collapse').on('shown.bs.collapse', function () {
$(this).parent().find(".glyphicon-chevron-up").removeClass("glyphicon-chevron-up").addClass("glyphicon-chevron-down");
}).on('hidden.bs.collapse', function () {
$(this).parent().find(".glyphicon-chevron-down").removeClass("glyphicon-chevron-down").addClass("glyphicon-chevron-up");
});
So sometimes it works, sometimes it does not. When both of them are open and I first close the second one, it also closes the first one.
Is that what you want?

I just changed the id of the second accordion and its data-parent value.
I'm new to jquery and I'm trying to figure out how to traverse the dom in order to toggle the collapse option on panel footers? Any pointers?

I created a project with Meteorjs and Bootstrap 3.
In this project, I can add dynamically bootstrap panels (or modals) to the Home page.
What bothers me is the fact that the position of theses panels (or modals) is random, I would like them to be organized. E.g.: when the screen of computer is medium, I want 3 panels (or modals) in each column.
Would you have an idea on how to do that?
The code is:
<template name="home">
{{> navigation}}
<div class="container-fluid lov">
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-3">
{{#each positions}}
{{> position}}
{{/each}}
</div>
</div>
</div>
</template>
And this is the JavaScript of this template:
Template.home.events ({
'dblclick .lov': function (e, tmpl) {
e.preventDefault();
e.stopPropagation();
if(e.target.className === 'container-fluid lov'){
var id = Positions.insert({ name:'Clique here to change the title', domaine:'ici tu ecris ton text en gros',footername:'le nom de pays et la ville si tu veux'});
Session.set('editing_table',id);
}
}
});
This is the collection:
Positions = new Meteor.Collection('positions');
This one is the code of position template that allow us to create our panel:
<template name="position">
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-3">
<div class="panel panel-default" id="{{_id}}" style="position:absolute;left:{{left}};top:{{top}}; width:350px">
<div class="panel-heading">
{{#if hadanata3ou}}
<a class="close" data-dismiss="modal">x</a>{{/if}}
{{#if editing_tablename}}
<input class="input input-medium tablename" value="{{name}}" type="text" />
{{else}}
<h6 class="tablename">{{name}}</h6>
{{/if}}
<!-- <h3 class="panel-title">Panel title</h3> -->
</div>
<div class="panel-body">
<div id="{{_id}}">
{{#if editing_field}}
<textarea class="input input-lg efield" name="efield" type="text">
{{domaine}}
</textarea>
{{else}}
<span>
{{domaine}}
</span>
{{/if}}
</div>
</div>
<div class="panel-footer">
{{#if editing_footer}}
<input class="input input-medium footer" value="{{footername}}" type="text" />
{{else}}
<p class="muted">{{footername}}</p>
{{/if}}
</div>
</div>
</div>
</div>
</template>
I'll be honest, I don't know a whole lot about meteorjs templating, but I can show you how the Bootstrap grid system works for rendering different amounts of panels based on the size of the view.
Bootstrap uses 4 different sizes:
Large lg (Desktop)
Medium md (Landscape Tablet)
Small sm (Portrait Tablet)
Extra Small xs (Mobile)
And using the classes .visible-SIZE and .hidden-SIZE, you can control what elements are shown/rendered at what sizes. For example:
<div class="container-fluid">
<div class="row visible-lg visible-md hidden-sm hidden-xs" >
<div class="col-lg-4 col-md-4">
<div class="panel panel-default">
<div class="panel-heading">
<h4><span class="hidden-lg visible-md">Panel One - Medium</span> <span class="hiddn-md visible-lg">Panel One - Large</span></h4>
</div>
</div>
</div>
<div class="col-lg-4 col-md-4">
<div class="panel panel-default">
<div class="panel-heading">
<h4><span class="hidden-lg visible-md">Panel Two - Medium</span> <span class="hiddn-md visible-lg">Panel Two - Large</span></h4>
</div>
</div>
</div>
<div class="col-lg-4 col-md-4">
<div class="panel panel-default">
<div class="panel-heading">
<h4><span class="hidden-lg visible-md">Panel Three - Medium</span> <span class="hiddn-md visible-lg">Panel Three - Large</span></h4>
</div>
</div>
</div>
</div>
<div class="row hidden-lg hidden-md visible-sm visible-xs">
<div class="col-sm-6 col-xs-6">
<div class="panel panel-default">
<div class="panel-heading">
<h4><span class="hidden-sm visible-xs">Panel One - Extra Small</span> <span class="hiddn-xs visible-sm">Panel One - Small</span></h4>
</div>
</div>
</div>
<div class="col-sm-6 col-xs-6">
<div class="panel panel-default">
<div class="panel-heading">
<h4><span class="hidden-sm visible-xs">Panel Two - Extra Small</span> <span class="hiddn-xs visible-sm">Panel Two - Small</span></h4>
</div>
</div>
</div>
</div>
</div>
This code renders a row of .panel panel-default <div> elements. When the view is md or lg, it renders 3 <div>'s, each with the class col-md-4 and col-lg-4. The total amount of columns you can have is 12, and a class with col-*-4 takes up 4 of those 12 slots. Therefore, 3 * 4 is 12, or 1 complete row. Same with 2 * 6 for the col-sm-6 and col-xs-6.
In your meterojs templates, you need to decide how to use these classes to render the correct amount of columns. It's not too difficult, but spend some time playing with it to get the layout you want. If you want to see the test layout in effect, check this link:
Bootply
And try resizing your browser window.
Hope that can provide you some insight into Bootstrap's grid layout, and how to render different columns depending on the size of your browser.
