Enabling Tab key navigation Tab item in Blazor Tabs Component

13 Jan 20233 minutes to read

The TabIndex property of a Tab item is used to enable tab key navigation for that particular item. When a positive value is assigned to the [TabIndex] property, it allows the user to switch focus to the next or previous tab item using the Tab or Shift+Tab keys. By default, the user can only switch between tab items using the arrow keys.

If the TabIndex value is set to 0 for all tab items, the tab will switch based on the order of the elements on the page. This means that if the tab items are listed in a specific order on the page, the user will be able to navigate through them using the Tab key in that same order.

To use the TabIndex property, you can assign a positive value to the property of each tab item that you want to enable tab key navigation.
