+    The repeater component creates a container to display information for a list of objects. A repeater list is particularly effective as an alternative to a grid layout in mobile-intensive contexts and other scenarios that require the compact display of information. Within the <stache-code>sky-repeater</stache-code> component, the <stache-code>sky-repeater-item</stache-code> component creates individual repeater items. Within the repeater items, the <stache-code>sky-repeater-item-title</stache-code> component displays a header, the <stache-code>sky-repeater-item-content</stache-code> component displays content text when the repeater is expanded, and the <stache-code>sky-repeater-item-context-menu</stache-code> wraps and styles <a stacheRouterLink="/components/dropdown">a <stache-code>sky-dropdown</stache-code> component</a>.
