Tabbed menus are widely used in video games and application UI to organize and present content. Tab and TabView are powerful controls that simplify the process of creating tabbed menus.

Example overview

This example demonstrates how to create tabbed menus in a sample scene and a custom Editor window. The menu has three tabs. Each tab presents certain content. When you select a tab, the content associated with that tab displays. The example also uses view data keys to preserve the tab orders for the Editor window.

A tabbed menu with three tabs: London, Paris, and Ottawa. Each tab displays a label with the capital city name and a description.

You can find the completed files that this example creates in this GitHub repository.

Prerequisites

This guide is for developers familiar with the Unity Editor, UI Toolkit, and C# scripting. Before you start, get familiar with the following:

Create a TabView

Create a UXML document and add a TabView to it.
  1. Create a project in Unity with any template.
  2. In the 
    Assets
    folder, create a UI Document named 
    TabbedMenu.uxml
    .
  3. Double-click 
    TabbedMenu.uxml
    to open it in the UI Builder.
  4. Drag a TabView from the Library to the Hierarchy panel.
  5. In the Inspector panel of the TabView, do the following:
    • Set View Data Key to 
      TabbedMenu
      .
    • Select the Reorderable checkbox.

Add tabs and tab content

Add three tabs to the TabView. For each tab, add a label as its child element which displays the tab content.
  1. Under TabView, add three Tabs.
  2. In the Inspector panel of each Tab, set Label to the following values:
    • London
      for the first Tab
    • Paris
      for the second Tab
    • Ottawa
      for the third Tab
  3. Set View Data Key to the following values:
    • LondonTab
      for the first Tab
    • ParisTab
      for the second Tab
    • OttawaTab
      for the third Tab
  4. In the Hierarchy panel, under each Tab, add a Label.
  5. In the Inspector panel of each Label, Set Text to the following values:
    • London is the capital city of England
      for the first Label
    • Paris is the capital of France
      for the second Label
    • Ottawa is the capital of Canada
      for the third Label

Define the tabbed menu styles

Define the layout for tabs and tab content using USS. You can style the tabs and the tab content the way you like. This example adds a background color for the selected tab and hides the tab header underline.
  1. In the 
    Assets
    folder, create a stylesheet named 
    TabbedMenu.uss
    .
  2. Open 
    TabbedMenu.uss
    and add the following styling rules:
    /* Style for tabs */.unity-tab__header {	background-color: rgb(229, 223, 223);	-unity-font-style: bold;	font-size: 14px;}/* Adds background color for the selected tab */.unity-tab__header:checked  {	background-color: rgb(173, 166, 166);}/* Style for tabContent */.tab-content {	background-color: rgb(255, 255, 255);	font-size: 20px;}/* By default, each tab header has an underline. This hides the header underline  */.unity-tab__header-underline {	opacity: 0; /* or rgba(0, 0, 0, 0); */}
  3. Double-click 
    TabbedMenu.uxml
    to open it in UI Builder.
  4. In the StyleSheets panel, select + > Add Existing USS.
  5. Select the USS file that you created earlier.
  6. Apply 
    .tab-content
    to each Label under Tab.
The finished 
TabbedMenu.uxml
looks like the following:
<ui:UXML xmlns:ui="UnityEngine.UIElements" xmlns:uie="UnityEditor.UIElements" xsi="http://www.w3.org/2001/XMLSchema-instance" engine="UnityEngine.UIElements" editor="UnityEditor.UIElements" noNamespaceSchemaLocation="../../UIElementsSchema/UIElements.xsd" editor-extension-mode="False">  /* Your src might look different. If you save your UXML in UI Builder, USS file is referenced by the file location, fileID and guid. */  <Style src="TabbedMenu.uss" />  <ui:TabView reorderable="true" view-data-key="TabbedMenu">     <ui:Tab label="London" view-data-key="LondonTab">         <ui:Label text="London is the capital city of England" class="tab-content"/>     </ui:Tab>     <ui:Tab label="Paris" view-data-key="ParisTab">         <ui:Label text="Paris is the capital of France"  class="tab-content"/>     </ui:Tab>     <ui:Tab label="Ottawa" view-data-key="OttawaTab">         <ui:Label text="Ottawa is the capital of Canada" class="tab-content"/>     </ui:Tab>  </ui:TabView></ui:UXML>

Use the tabbed menu in a game

Create a Panel Renderer GameObject in the SampleScene and add the UXML asset as the source asset. For demo purpose, there is no need to create and attch a Monobehaviour script to the GameObject.
  1. In the SampleScene, select
    GameObject

    ?

    > UI Toolkit > Panel Renderer.
  2. Select Panel Renderer in the SampleScene.
  3. In the
    Inspector

    ?

    window, select TabbedMenu.uxml from the Source Asset list.
  4. Enter Play mode.
  5. Select different tabs to see different contents.
  6. Drag the tabs to reorder them.

Use the tabbed menu in an Editor window

Create a custom Editor window and add the tabbed menu to it. You can drag the tabs to reorder them. The tab orders are saved when you close and reopen the Editor window.
  1. In the 
    Assets
    folder, create a folder named 
    Editor
    .
  2. In the 
    Editor
    folder, create a C# script named 
    TabbedMenuEditorWindow.cs
    with the following content:
    using UnityEditor;using UnityEngine;using UnityEngine.UIElements;public class TabbedMenuEditorWindow : EditorWindow{    [MenuItem("UI Toolkit Examples/Tabbed Menu")]    public static void ShowExample()    {        TabbedMenuEditorWindow wnd = GetWindow<TabbedMenuEditorWindow>();        wnd.titleContent = new GUIContent("Tabbed Menu");    }    public void OnEnable()    {        VisualElement root = rootVisualElement;        // Import UXML        var visualTree = AssetDatabase.LoadAssetAtPath<VisualTreeAsset>("Assets/TabbedMenu.uxml");        VisualElement tabbedMenuUXML = visualTree.Instantiate();        root.Add(tabbedMenuUXML);    }}
  3. In the Editor, select Window > Tabbed Menu.
  4. Select different tabs to see different contents.
  5. Drag the tabs to reorder them.
  6. Close the Editor window and reopen it. The tabs orders are saved.
