Redlines: We don't include redline comps because it's always more accurate to use developer tools to inspect the coded components, or a plugin such as the Prism Redline Tool.

Usage
When to use an accordion component:
- If users will only need a few specific pieces of content within a page.
- If you have only a small space to display a lot of content.
When not to use an accordion component:
- If users need to see most or all of the information on a page. Use well-formatted text instead.
- If there is not enough content to warrant condensing. Accordions increase cognitive load and interaction cost, as users have to make decisions about what headers to click on.
Accordion
Content creators should be able to decide if one or more of an accordion's sections are open in its default state. Note that a Show One Accordion could not have more than one section open, by default.
The arrow of an accordion section points toward the current location of that section's content. When the section is closed, the arrow points to the right to indicate that the content is hidden within the link/heading. When an accordion section is open, the arrow points down at the exposed content.
Users can select anywhere on the row of an accordion link/heading to toggle that section open and closed.
Keyboard operation:i
- Space or Enter = When focus is on the accordion header of a collapsed section, expands the section. When focus is on the header of an expanded section, collapses the section (unless one section must be open at all times).
- Tab = Moves focus to the next focusable element. All focusable elements in the accordion are included in the page Tab sequence.
- Shift + Tab = Moves focus to the previous focusable element. All focusable elements in the accordion are included in the page Tab sequence.
- Down Arrow = When focus is on an accordion header, moves focus to the next accordion header. When focus is on last accordion header, either does nothing or moves focus to first accordion header.
- Up Arrow = When focus is on an accordion header, moves focus to the previous accordion header. When focus is on first accordion header, either does nothing or moves focus to last accordion header.
- Home = When focus is on an accordion header, moves focus to the first accordion header.
- End = When focus is on an accordion header, moves focus to the last accordion header.
Show More / Show Less
When the user selects a "Show More" link option, it retains its position at the end of the content that's revealed, and is replaced with "Show Less".

purpose, align label with the task the user is attempting.
