Collapsibles
Collapsibles are used to enable animated toggle behavior to elements with selected applied classes.
Any div
element can be turned into a collapsible element simply by applying a collapse
class on the element. Afterwards, the collapsible element can be toggled by using one of the following methods.
Applying a class collapse-open
alongside the collapse
displays the collapsible element content, which is hidden by default. The triggering action button toggles between the two states depending on the status of the collapsible element - it shows the collapsible element content when it is hidden, or hides it when it it is already visible.
Usage
Collapsible functionality can be enabled and controlled using HTML data attributes
or Javascript
.
Via data attributes
A collapsible element can be controlled simply by adding a data-toggle="collapse"
on a button, along with a data-href="#id"
where target
is the targeted collapsible element id
.
Code output
Collapsible title
Collapsible content
HTML Markup
Copy<button class="btn btn-main" data-toggle="collapse" data-href="#collapsible-example">Collapsible element toggle</button>
<div id="collapsible-example" class="collapse">
<div class="box pad-md">

can be called using Javascript.
