Where It Fits

CometChatGroups is a directory list component. It renders available groups and emits the selected CometChat.Group via onItemClick. Wire it to CometChatMessageHeader, CometChatMessageList, and CometChatMessageComposer to build a group chat layout.

import { useState } from "react";
import {
  CometChatGroups,
  CometChatMessageHeader,
  CometChatMessageList,
  CometChatMessageComposer,
} from "@cometchat/chat-uikit-react";
import { CometChat } from "@cometchat/chat-sdk-javascript";
import "@cometchat/chat-uikit-react/css-variables.css";

function GroupChatApp() {
  const [selectedGroup, setSelectedGroup] = useState<CometChat.Group>();

  return (
    <div style={{ display: "flex", height: "100vh", width: "100vw" }}>
      <div style={{ width: 480, height: "100%" }}>
        <CometChatGroups
          onItemClick={(group: CometChat.Group) => setSelectedGroup(group)}
        />
      </div>
      {selectedGroup ? (
        <div style={{ flex: 1, display: "flex", flexDirection: "column" }}>
          <CometChatMessageHeader group={selectedGroup} />
          <CometChatMessageList group={selectedGroup} />
          <CometChatMessageComposer group={selectedGroup} />
        </div>
      ) : (
        <div style={{ flex: 1, display: "grid", placeItems: "center", background: "#F5F5F5", color: "#727272" }}>
          Select a group
        </div>
      )}
    </div>
  );
}

Minimal Render

import { CometChatGroups } from "@cometchat/chat-uikit-react";
import "@cometchat/chat-uikit-react/css-variables.css";

function GroupsDemo() {
  return (
    <div style={{ width: "100%", height: "100%" }}>
      <CometChatGroups />
    </div>
  );
}

export default GroupsDemo;

Root CSS class: .cometchat-groups

Filtering Groups

Pass a CometChat.GroupsRequestBuilder to groupsRequestBuilder. Pass the builder instance — not the result of .build().

import { CometChatGroups } from "@cometchat/chat-uikit-react";
import { CometChat } from "@cometchat/chat-sdk-javascript";

function FilteredGroups() {
  return (
    <CometChatGroups
      groupsRequestBuilder={
        new CometChat.GroupsRequestBuilder()
          .joinedOnly(true)
          .setLimit(10)
      }
    />
  );
}

Filter Recipes

Recipe	Code
Joined groups only	`new CometChat.GroupsRequestBuilder().joinedOnly(true)`
Limit to 10 per page	`new CometChat.GroupsRequestBuilder().setLimit(10)`
Search by keyword	`new CometChat.GroupsRequestBuilder().setSearchKeyword("design")`
Filter by tags	`new CometChat.GroupsRequestBuilder().setTags(["vip"])`
With tags data	`new CometChat.GroupsRequestBuilder().withTags(true)`

Default page size is 30. The component uses infinite scroll — the next page loads as the user scrolls to the bottom. The searchRequestBuilder prop accepts a separate GroupsRequestBuilder for filtering when the search bar is active.

import { CometChatGroups } from "@cometchat/chat-uikit-react";
import { CometChat } from "@cometchat/chat-sdk-javascript";

function SearchFilteredGroups() {
  return (
    <CometChatGroups
      searchRequestBuilder={
        new CometChat.GroupsRequestBuilder()
          .setLimit(5)
          .setSearchKeyword("team")
      }
    />
  );
}

Refer to GroupsRequestBuilder for the full builder API.

Actions and Events

Callback Props

onItemClick

Fires when a group row is tapped. Primary navigation hook — set the active group and render the message view.

import { CometChatGroups } from "@cometchat/chat-uikit-react";
import { CometChat } from "@cometchat/chat-sdk-javascript";

function GroupsWithClick() {
  const handleItemClick = (group: CometChat.Group) => {
    console.log("Selected:", group.getGuid());
  };

  return <CometChatGroups onItemClick={handleItemClick} />;
}

onSelect

Fires when a group is checked/unchecked in multi-select mode. Requires selectionMode to be set.

import { useState } from "react";
import {
  CometChatGroups,
  SelectionMode,
} from "@cometchat/chat-uikit-react";
import { CometChat } from "@cometchat/chat-sdk-javascript";

function BatchSelectGroups() {
  const [selected, setSelected] = useState<Set<string>>(new Set());

  const handleSelect = (group: CometChat.Group, isSelected: boolean) => {
    setSelected((prev) => {
      const next = new Set(prev);
      const id = group.getGuid();
      isSelected ? next.add(id) : next.delete(id);
      return next;
    });
  };

  return (
    <CometChatGroups
      selectionMode={SelectionMode.multiple}
      onSelect={handleSelect}
    />
  );
}

onError

Fires on internal errors (network failure, auth issue, SDK exception).

import { CometChatGroups } from "@cometchat/chat-uikit-react";
import { CometChat } from "@cometchat/chat-sdk-javascript";

function GroupsWithErrorHandler() {
  return (
    <CometChatGroups
      onError={(error: CometChat.CometChatException) => {
        console.error("CometChatGroups error:", error);
      }}
    />
  );
}

Global UI Events

CometChatGroupEvents emits events subscribable from anywhere in the application. Subscribe in a useEffect and unsubscribe on cleanup.

Event	Fires when	Payload
`ccGroupCreated`	A new group is created	`CometChat.Group`
`ccGroupDeleted`	A group is deleted	`CometChat.Group`
`ccGroupMemberJoined`	A user joins a group	`IGroupMemberJoined`
`ccGroupLeft`	A user leaves a group	`IGroupLeft`
`ccGroupMemberAdded`	Members are added to a group	`IGroupMemberAdded`
`ccGroupMemberScopeChanged`	A member’s scope changes	`IGroupMemberScopeChanged`
`ccGroupMemberKicked`	A member is kicked	`IGroupMemberKickedBanned`
`ccGroupMemberBanned`	A member is banned	`IGroupMemberKickedBanned`
`ccGroupMemberUnbanned`	A member is unbanned	`IGroupMemberUnBanned`
`ccOwnershipChanged`	Group ownership is transferred	`IOwnershipChanged`

import { useEffect } from "react";
import { CometChatGroupEvents } from "@cometchat/chat-uikit-react";
import { CometChat } from "@cometchat/chat-sdk-javascript";

function useGroupEvents() {
  useEffect(() => {
    const createdSub = CometChatGroupEvents.ccGroupCreated.subscribe(
      (group: CometChat.Group) => {
        console.log("Group created:", group.getName());
      }
    );
    const deletedSub = CometChatGroupEvents.ccGroupDeleted.subscribe(
      (group: CometChat.Group) => {
        console.log("Group deleted:", group.getName());
      }
    );
    const memberAddedSub = CometChatGroupEvents.ccGroupMemberAdded.subscribe(
      (item) => {
        console.log("Members added to:", item.userAddedIn.getName());
      }
    );
    const leftSub = CometChatGroupEvents.ccGroupLeft.subscribe(
      (item) => {
        console.log("User left group:", item.leftGroup.getName());
      }
    );

    return () => {
      createdSub?.unsubscribe();
      deletedSub?.unsubscribe();
      memberAddedSub?.unsubscribe();
      leftSub?.unsubscribe();
    };
  }, []);
}

SDK Events (Real-Time, Automatic)

The component listens to these SDK events internally. No manual attachment needed unless additional side effects are required.

SDK Listener	Internal behavior
`onGroupMemberJoined`	Updates member count, sets `hasJoined` if current user joined
`onGroupMemberLeft`	Updates member count, sets `hasJoined(false)` if current user left
`onMemberAddedToGroup`	Updates member count, adds group to list if current user was added
`onGroupMemberKicked`	Updates member count, sets `hasJoined(false)` if current user was kicked
`onGroupMemberBanned`	Removes group if current user was banned, otherwise updates member count
`onGroupMemberScopeChanged`	Updates scope if current user’s scope changed, updates member count

In React 18 StrictMode, useEffect runs twice on mount in development. The component handles listener cleanup internally, but any additional listeners added alongside the component need cleanup in the useEffect return function to avoid duplicate event handling.

Custom View Slots

Each slot replaces a section of the default UI. Slots that accept a group parameter receive the CometChat.Group object for that row.

Slot	Signature	Replaces
`itemView`	`(group: CometChat.Group) => JSX.Element`	Entire list item row
`leadingView`	`(group: CometChat.Group) => JSX.Element`	Avatar / left section
`titleView`	`(group: CometChat.Group) => JSX.Element`	Name / title text
`subtitleView`	`(group: CometChat.Group) => JSX.Element`	Member count subtitle
`trailingView`	`(group: CometChat.Group) => JSX.Element`	Right section
`headerView`	`JSX.Element`	Entire header bar
`loadingView`	`JSX.Element`	Loading spinner
`emptyView`	`JSX.Element`	Empty state
`errorView`	`JSX.Element`	Error state
`options`	`(group: CometChat.Group) => CometChatOption[]`	Context menu / hover actions

// CometChatOption interface
interface CometChatOption {
  id?: string;       // Unique identifier
  title?: string;    // Display text
  iconURL?: string;  // Icon asset URL
  onClick?: () => void; // Click handler
}

Common Patterns

Custom empty state with CTA

import { CometChatGroups } from "@cometchat/chat-uikit-react";

function EmptyStateGroups() {
  return (
    <CometChatGroups
      emptyView={
        <div style={{ textAlign: "center", padding: 40 }}>
          <p>No groups available</p>
          <button onClick={() => { /* navigate to create group */ }}>
            Create a group
          </button>
        </div>
      }
    />
  );
}

Hide all chrome — minimal list

import { CometChatGroups } from "@cometchat/chat-uikit-react";

function MinimalGroups() {

import { CometChat } from "@cometchat/chat-sdk-javascript";

function JoinedGroups() {
  return (

CSS Architecture

The component uses CSS custom properties (design tokens) defined in @cometchat/chat-uikit-react/css-variables.css. The cascade:

Global tokens (e.g., --cometchat-primary-color, --cometchat-background-color-01) are set on the .cometchat root wrapper.
Component CSS (.cometchat-groups) consumes these tokens via var() with fallback values.
Overrides target .cometchat-groups descendant selectors in a global stylesheet.

To scope overrides to a single instance when multiple CometChatGroups exist on the same page, wrap the component in a container and scope selectors:

.sidebar-left .cometchat-groups .cometchat-avatar {
  border-radius: 8px;
}
