Using bootstrap.collapse

Enable via javascript:

$(".collapse").collapse()

Options

Name type default description
parent selector false If selector then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior)
toggle boolean true Toggles the collapsible element on invocation

Markup

Just add data-toggle="collapse" and a data-target to element to automatically assign control of a collapsible element. The data-target attribute accepts a css selector to apply the collapse to. Be sure to add the class collapse to the collapsible element. If you'd like it to default open, add the additional class in.

<button class="btn btn-danger" data-toggle="collapse" data-target="#demo">
  simple collapsible
</button>

<div id="demo" class="collapse in"> … </div>
Heads up! To add accordion-like group management to a collapsible control, add the data attribute data-parent="#selector". Refer to the demo to see this in action.

Events

Bootstrap's collapse class exposes a few events for hooking into collapse functionality.

Event Description
show This event fires immediately when the show instance method is called.
shown This event is fired when a collapse element has been made visible to the user (will wait for css transitions to complete).
hide This event is fired immediately when the hide method has been called.
hidden This event is fired when a collapse element has been hidden from the user (will wait for css transitions to complete).
$('#myCollapsible').on('hidden', function () {
  // do something…
})
