List Item

Selectable row with icon slots, used on its own or as the option of list and select.

c2-list-item is the row that c2-list and c2-select are built from. On its own it is a self-contained toggle: a click, Enter or Space flips selected and fires selected-change. Inside a c2-list the list takes over: it matches each row’s value against its own, sets selected for you and handles the keyboard, so rows in a list never carry the attribute themselves. The default slot is the content, description a second muted line; prefix-icon and suffix-icon take an inline SVG, a c2-feather-* icon or a c2-mat-icon and are sized by --c2-list-item__icon--size. href turns the row into a link. label is the short text a select shows in its trigger when the row content is richer than a line of text. Rows expose role="button" with aria-pressed on their own and role="option" with aria-selected inside a list, and draw a focus ring for keyboard users.

Installation

npm install @c2n/list-item

Usage

Rows stretch to their container, so give the wrapper a width. Hover, selected and disabled each have their own set of variables.

Behaviour

  • Standalone: a click toggles selected and fires selected-change with detail.selected and detail.value.
  • In a list: the click bubbles to the c2-list, which updates its value and pushes the selected state back down. Listen to selection-change on the list (or the select) instead.
  • Adjacent selection: in a multiple list, selected rows that touch lose the corner radius between them and read as one block; a selected row on its own keeps its full radius.
  • Keyboard: a standalone row is a tab stop; Enter and Space toggle it. In a list the list moves focus with the arrow keys and selects with Enter or Space.
  • description: a second line under the content, muted and smaller; label keeps the select trigger to the first line.
  • href: the row renders as a link (role="link"); inside a list it still takes part in the selection.
  • label: what a c2-select shows for the row. Without it the trigger shows the row’s text content, which for a two-line row would be both lines.
  • data: any object you attach to the row; a list or select returns it in selection-change next to the value.
const item = document.querySelector('c2-list-item')
item.addEventListener('selected-change', (event) => {
  console.log(event.detail) // { selected: true, value: 'inbox' }
