Keyboard interaction
The tree view takes a single tab stop, with focusing landing on the selected node or the first node of an unselected tree. When trees have focus, arrow keys provide navigation. The Right arrow key expands a closed branch node. If a branch is open, the Right arrow moves into the first child node. Pressing the Left arrow key on an open branch collapses it. Left arrowing on a child moves the focus to the parent branch. Up and Down arrow keys move vertically through open branches and their child nodes. A node or branch is selected by Space or Enter keys.
- The component uses a
treerole on aulwith all nodes inligiven a role oftreeitemwith atabindex="-1"andaria-selected="false"(except the currently selected node). - All branch nodes contain an
aria-expandedattribute. - See the ARIA authoring practice Tree View pattern for more considerations.
