size

A tree view offers four sizes: small, medium, large and extra-large. Medium is the default and most common. Use other sizes sparingly to create a visual hierarchy of importance on the page.

isDetached

When placed outside a panel, a tree view uses the detached style with rounded corners. Inside a panel, it spans edge to edge by default and does not include rounded corners.

showDragIcon

Tree view items can include a drag icon when needed. The icon serves as a keyboard-navigable indicator for items that support multiple actions. It appears only on hover, active and keyboard focus states.

selectionMode

The type of selection allowed in a collection can be none, single or multiple.

• None: tree view does not allow item selection by default.
• Single: users can select only one item at a time.
• Multiple: users can select more than one item at a time.

selectionStyle

• Checkbox With checkboxes, both single-select and multi-select views display boxes on the left of each item. Clicking another item adds it to the selection, and clicking a selected item removes it.
• Highlight Use highlight selection when checkboxes add clutter or unnecessary controls. This style shows a highlighted state for selected items, and clicking a new item replaces the previous selection by default.

All tree views have a hover state, regardless of whether actions or selections can be made.

selectionBehavior

Tree views support both single-select and multi-select modes, using either checkbox or highlight styles. In multi-select mode, selecting an item toggles its selection on or off. In single-select mode, selecting an item replaces the current selection.
