# Message Header

> Message Header — CometChat documentation.

## Overview

`MessageHeader` is a [Component](/ui-kit/angular/components-overview#components) that showcases the [User](/sdk/javascript/users-overview) or [Group](/sdk/javascript/groups-overview) details in the toolbar. Furthermore, it also presents a typing indicator and a back navigation button for ease of use.

The `MessageHeader` is comprised of the following components:

| Components                                      | Description                                                                                                                                    |
| ----------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| [ListItem Component](/ui-kit/angular/list-item) | This component’s view consists of avatar, status indicator , title, and subtitle. The fields are then mapped with the SDK’s user, group class. |
| Back Button                                     | BackButton that allows users to navigate back from the current activity or screen to the previous one                                          |

### Actions

[Actions](/ui-kit/angular/components-overview#actions) dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.

##### 1. OnBack

`OnBack` is triggered when you click on the back button of the Message Header component. You can override this action using the following code snippet.

**Example**

In this example, we are employing the `onBack` action.

<Tabs>
  <Tab title="app.component.ts">
    ```ts theme={null}
    import { Component, OnInit } from '@angular/core';
    import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
    import "@cometchat/uikit-elements";

    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent implements OnInit{

      ngOnInit(): void {
        CometChat.getUser("uid").then((user:CometChat.User)=>{
          this.userObject=user;
        });
      }

      public userObject!: CometChat.User;

      constructor(private themeService:CometChatThemeService) {
        themeService.theme.palette.setMode("light")
        themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
      }

      public handleOnBack = () => {
        console.log("Your custom on back action");
      }

      onLogin(UID?: any) {
        CometChatUIKit.login({ uid: UID }).then(
          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },
          (error) => {
            console.log("Login failed with exception:", { error });
          }
        );
      }
    }
    ```
  </Tab>

  <Tab title="app.component.html">
    ```html theme={null}
    <div class="fullwidth">
      <cometchat-message-header
        *ngIf="userObject"
        [user]="userObject"
        [onBack]="handleOnBack"
      ></cometchat-message-header>
    </div>
    ```
  </Tab>
</Tabs>

***

##### 2. OnError

This action doesn't change the behavior of the component but rather listens for any errors that occur in the Message Header component.

**Example**

In this example, we are employing the `onError` action.

<Tabs>
  <Tab title="app.component.ts">
    ```ts theme={null}
    import { CometChat } from '@cometchat/chat-sdk-javascript';
    import { Component, OnInit } from '@angular/core';
    import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
    import "@cometchat/uikit-elements";

    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent implements OnInit{

      ngOnInit(): void {
        CometChat.getUser("uid").then((user:CometChat.User)=>{
          this.userObject=user;
        });
      }

      public userObject!: CometChat.User;

      constructor(private themeService:CometChatThemeService) {
        themeService.theme.palette.setMode("light")
        themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
      }

      public handleOnError = (error: CometChat.CometChatException) => {
        console.log("your custom on error action", error);
      };

      onLogin(UID?: any) {
        CometChatUIKit.login({ uid: UID }).then(
          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },
          (error) => {
            console.log("Login failed with exception:", { error });
          }
        );
      }
    }
    ```
  </Tab>

  <Tab title="app.component.html">
    ```html theme={null}
    <div class="fullwidth">
      <cometchat-message-header
        *ngIf="userObject"
        [user]="userObject"
        [onError]="handleOnError"
      ></cometchat-message-header>

### Filters

**Filters** allow you to customize the data displayed in a list within a `Component`. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using `RequestBuilders` of Chat SDK.

The `MessageHeader` component does not have any exposed filters.

### Events

[Events](/ui-kit/angular/components-overview#events) are emitted by a `Component`. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed.

The `MessageHeader` component does not produce any events.

## Customization

To fit your app's design requirements, you can customize the appearance of the Message Header component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

### Style

Using Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component.

##### 1. MessageHeader Style

To customize the appearance, you can assign a `MessageHeaderStyle` object to the `MessageHeader` component.

**Example**

In this example, we are employing the `MessageHeaderStyle`.

These are a set of small functional customizations that allow you to fine-tune the overall experience of the component. With these, you can change text, set custom icons, and toggle the visibility of UI elements.

Here is a code snippet demonstrating how you can customize the functionality of the Message Header component.

### Advanced

For advanced-level customization, you can set custom views to the component. This lets you tailor each aspect of the component to fit your exact needs and application aesthetics. You can create and define your views, layouts, and UI elements and then incorporate those into the component.

#### ListItemView

The `MessageHeader` component consists of a `listItemView`. You can customize the ListItem according to your requirements by using the `listItemView` property.
