Collapsers

Collapsers are expandable elements that hide page content until you trigger it open. We use collapsers to hide content in very long documents, out of consideration for our readers. Each collapser has a title (what we show to readers), but also an id that we use for deep "anchor" links to specific collapsers.

Here's an example collapser:

Here are some examples of when to use collapsers in your document.

Create a collapser

To create a collapser, you'll need to use our collapser code.

Here's an example of the collapser source:

<CollapserGroup>
  <Collapser
    id="collapser-source"
    title="Collapser source"
  >
    <dl class="collapser-list">

    <dt id="collapser-1">Collapser 1</dt>
    <dd>
        <p>This is the first example collapser.</p>
    </dd>

    <dt id="collapser-2">Collapser 2</dt>
    <dd>
        <p>This is the second example collapser.</p>
    </dd>
    </dl>  
  </Collapser>
</CollapserGroup>

Collapsers triggers

To open or close a collapser:

• Click the open buttons or Show/Hide All.
• Arrive at an individual collapser via an anchor ID. For example, go directly to Collapser 1 in the example above.
• Type the shortcut key s to show (open) all collapsers on the page.
• Use CMD+F (or CTRL+F) to find in page and all the collapsers will open automatically.
