Details is an expandable panel for showing and hiding content from the user to make the UI less crowded. Details consists of a summary and a content area.

The Summary is the part that is always visible, and typically describes the contents, for example, with a title. Clicking on the summary toggles the content area’s visibility. The summary supports rich content and can contain any component. This can be utilized for example to indicate the status of the corresponding content.

The content area is the collapsible part of Details. It can contain any component. When the content area is collapsed, the content is invisible and inaccessible by keyboard or screen reader.
