Splitter - Keyboard Navigation

Pane 1

Hold the left or right arrow to resize the splitter bar or press Enter to collapse it.

Pane 2

Hold the left or right arrow to resize the splitter bar or press Enter to collapse it.

Pane 3

You can resize this pane too. Since the nearest pane to a split bar is Pane 2, you cannot collapse this pane, but you can resize it to a zero size because it does not have a Min setting.

  • Left Moves left a splitter bar in a horizontal Splitter.
  • Right Moves right a splitter bar in a horizontal Splitter.
  • Enter Toggles the collapsed state of the nearest collapsible pane.


  • The splitter panes render a tabIndex="0" so they are focusable and the browser adds them to the "tab" sequence.
  • Double-click on a splitter bar, or pressing Enter when it is focused, collapses the closest collapsible pane (usually the one before the bar). Clicking or tapping the directional arrows on the bar lets you choose which pane to collapse.


Keyboard navigation provides all web and app users with a fast keyboard-only navigation capability and is also part of the web accessibility features - it enables users with disabilities to fully control their website or app access through the keyboard.

By default, users can only navigate to links, buttons, and form controls with a keyboard. The navigation order in which interactive items receive keyboard focus has to be logical and intuitive. Generally, keyboard navigation logic needs to follow the visual horizontal and vertical flow of the page, for example, left to right and top to bottom, header first followed by the main and then the page navigation.

The keyboard navigation of the Telerik UI for Blazor Splitter is always enabled, as demonstrated in this demo.

This Blazor Splitter Keyboard Navigation example is part of a unique collection of hundreds of Blazor demos, with which you can see all Telerik UI for Blazor components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for Blazor or ThemeBuilder.
