Creates a collapsible block of content.

To create a collapsible block of content, create a container and add the data-role=”collapsible” attribute. Using data-content-theme attribute allows you to set a theme for the content of the collapsible. Directly inside this container, add any header (H1-H6) or legend element. The framework will style the header to look like a clickable button and add a “+” icon to the left to indicate it’s expandable. After the header, add any HTML markup you want to be collapsible. The framework will wrap this markup in a container that will be hidden/shown when the heading is clicked.
