ThreadList

Switch between conversations. Supports sidebar or dropdown layouts.

This demo uses ThreadListSidebar, which includes thread-list as a dependency and provides a complete sidebar layout. For custom implementations, you can use thread-list directly.

Getting Started

Add the component

Use threadlist-sidebar for a complete sidebar layout or thread-list for custom layouts.

} from "@/components/ui/sidebar";

export default function Assistant() {
  return (
    <SidebarProvider>
      <div className="flex h-dvh w-full">
        <ThreadListSidebar />
        <SidebarInset>

Anatomy

The ThreadList component is built with the following primitives:

import { ThreadListPrimitive, ThreadListItemPrimitive } from "@assistant-ui/react";

<ThreadListPrimitive.Root>
  <ThreadListPrimitive.New />
  <ThreadListPrimitive.Items>
    {() => (
      <ThreadListItemPrimitive.Root>
        <ThreadListItemPrimitive.Trigger>
          <ThreadListItemPrimitive.Title />
        </ThreadListItemPrimitive.Trigger>
        <ThreadListItemPrimitive.Archive />
        <ThreadListItemPrimitive.Delete />
      </ThreadListItemPrimitive.Root>
    )}
  </ThreadListPrimitive.Items>
</ThreadListPrimitive.Root>
