A component for displaying nested hierarchical information, such as a table of contents or directory structure.

An element that pops up from another element over other content; it differs from a tooltip in that it is usually triggered via click instead of hover and can contain interactive elements.

Ratings let users see and/or set a star rating for a product or other item.

An accordion is a vertical stack of interactive headings used to toggle the display of further information; each item can be 'collapsed' with just a short label visible or 'expanded' to show the full content.

Quotes are used to display a quotation: either from a person or another outside source or to highlight a passage of the current document (a pull quote).

Pagination is the process of splitting information over multiple pages instead of showing it all on a single page; also the name for the interface component used for navigating between these pages.

Tabbed interfaces are a way of navigating between multiple panels, reducing clutter and fitting more into a smaller space.

Buttons trigger an action such as submitting a form or showing/hiding an interface component.
