问题
I need to handle panel collapse behavior without using ID or data attributes. Ideally by setting a "collapsible" class on the parent div that can collapse its content, and a click on the heading should trigger the collapse
Here's the target HTML I'd like to write to handle collapse behavior automatically
<div class="panel-group collapse-all-but-one">
<div class="panel panel-primary panel-collapsible>
<div class="panel-heading">Click me to collapse</div>
<div class="panel-body">I will collaaaaaaapse</div>
</div>
<div class="panel panel-warning panel-collapsible">
<div class="panel-heading">Hey another one</div>
<div class="panel-body">I will close when the other one opens</div>
</div>
</div>

Here's my magic piece of code (the ready stuff ensures compatibility with rails/angularJS)
var ready
ready = function(){
$(".panel-collapsable")
.children(".panel-heading")
.click(function(){
var group = $(this).parent().parent()
if (group.hasClass("panel-group one-at-a-time")){
group.children(".panel").children(".panel-body")
.collapse('hide')
}
$(this)
.next('.panel-body')
.collapse('toggle')
})
}
$(document).ready(ready);
$(document).on('page:load', ready);
Remember to add some bootstrap classes like .collapse .in or .collapsed to initialize correct behaviour or the first click isn't going to do anything.
<div class="panel-body collapse in">I am expanded on page load</div>
...
<div class="panel-body collapse">I am collapsed on page load</div>
