The rule

Expandable pills require three elements to function correctly.

These are a toggle state, a way to deactivate other pills, and a single shared container. This container holds the expanded content for all pills.

Expandable pills need a toggle state. This state shows if a pill is open or closed. The pills also need a way to deactivate siblings. This means when one pill opens, others close. All expandable pills must share one container. This container sits below the group of pills. Using one container prevents too much code on the page.

A designer creates a webpage with a list of categories. Each category is an expandable pill. When a user clicks one category, its details appear below. Other open categories automatically close. This design uses one container for all category details, not a separate container for each one.
