Chat List Item

Props

• current: boolean (default: false) -- marks this item as the currently selected conversation
• children: slot (required) -- typically a ChatMessage component
• ...restProps: unknown -- additional attributes spread onto the <li> element

Keyboard Interactions

• Tab: Focus the interactive element within the list item
• Enter: Activate the focused list item or link
• (Keyboard interactions are primarily handled by the interactive content within)

ARIA

• Implicit listitem role from <li> element
• aria-current="true" when the current prop is provided, indicating the active conversation

When to Use

• Use inside a ChatList component to represent one chat conversation entry.
• Use when each conversation needs to be selectable and navigable.
• Use with the current prop to mark the currently active conversation.

When Not to Use

• Do not use outside of a ChatList context -- ChatListItem expects to be part of the ChatNav composition pattern.
• Do not use for non-chat list items -- use ContentsListItem for page section links or TimelineListItem for events.

Headless

This component provides an <li> element with optional aria-current for the active conversation, with zero visual styling. The consumer is responsible for all CSS including layout, selected state styling, hover effects, and spacing.

Styles

The consumer provides all CSS styling. The component renders with a .chat-list-item class for targeting. No default styles are included -- this is a fully headless component.

Testing

• Verify the component renders an <li> element with class chat-list-item
• Verify aria-current is rendered when current prop is true
• Verify keyboard interactions work correctly
• Verify pass-through attributes are applied

Advice

• Designers: Provide clear visual distinction between the selected conversation and others. Show hover and focus states. Consider showing unread message indicators, timestamps, and message previews.
• Developers: Use the current prop to mark the active conversation. Place a ChatMessage component as the child content.

Implementation Notes

• Renders an <li> element for list item semantics
• Consumer places a ChatMessage component as a child
• Supports current prop for marking the currently selected conversation
• aria-current rendered when the current prop is provided
• Spreads restProps onto the <li> for consumer customization

Composition

ChatListItem is part of the ChatNav composition pattern:

• ChatNav -- outer <nav> container providing the navigation landmark and accessible label.
• ChatList -- <ol> list conveying the ordered relationship of chat entries.
• ChatListItem -- individual <li> items, each typically containing a ChatMessage component.
• ChatMessage -- <article> element displaying one chat message with author, time, and content.

Related components

• chat-nav — a navigation container for chat information
• chat-list — an ordered list of chat list item components
• chat-message — a chat message shows one chat conversation message entry and all its data, including the author avatar, author name, time, etc.
