Collapsible containers

This is a series of div containers, each containing a heading and some content. JavaScript enhances the markup, collapsing all containers and inserting buttons inside the headings to toggle them open/closed. The JavaScript looks for the presence of the data attribute data-component="collapsibles" on the outer container and data-heading="collapsibles" on the headings.

The collapsible containers component is used within the group list component:

¶Considerations

Buttons shouldn't use the pointer cursor, so ensure the buttons have sufficient affordance by other visual means, such as background colour, border and/or box-shadow styles.
