Show / Hide Section Block

Display an accessible show/hide interface with details and summary elements.

Description

Show / Hide Section Block provides two blocks: a Show / Hide Group block that is populated with one or more Show / Hide Section blocks.

The HTML output for an individual section is:

<!-- Each section block has a details element. -->
<details>
	<!-- Each details element has a summary and additional, collapsible content. -->
	<summary>Summary text</summary>
	<!-- Additional inner blocks of any type are populated here. -->
</details>

The HTML output for the group is:

<div>
	<details>
		<summary></summary>
		<!-- Additional blocks to be shown/hidden -->
	</details>
	<details>
		<summary></summary>
		<!-- Additional blocks to be shown hidden -->
	</details>
	<!-- Additional section blocks -->
</div>

An option is provided in the block's side panel to toggle an "Open all"/"Close all" button. If this is toggled on for a block, an additional <button> element will be inserted and JavaScript will be used on the front-end to control the show/hide behavior of all <details> elements in the group at once.

If the toggle is off, no JavaScript is loaded on the front end.
