# tabViewSidebarHeader(content:) Adds a custom header to the sidebar of a tab view. ``` nonisolated func tabViewSidebarHeader(@ContentBuilder content: () -> Content) -> some View where Content : View ``` ## Discussion The header appears at the top of the sidebar before any tab labels and can scroll with the content. The header is only visible when the [`TabView`](/documentation/SwiftUI/TabView) is displaying the sidebar. The following example adds a welcome message to the top of the sidebar: ``` TabView { Tab("Home", systemImage: "house") { HomeView() } Tab("Alerts", systemImage: "bell") { AlertsView() } Tab("Browse", systemImage: "list.bullet") { MyBrowseView() } } .tabViewStyle(.sidebarAdaptable) .tabViewSidebarHeader { WelcomeHeaderView() } ``` > Note: To have a sidebar, a``doc://com.apple.SwiftUI/documentation/SwiftUI/TabView`` needs the > ``doc://com.apple.SwiftUI/documentation/SwiftUI/TabViewStyle/sidebarAdaptable`` style. --- Copyright © 2026 Apple Inc.
