Expand Button

Expand buttons enable end-users to expand or collapse nodes. These buttons are displayed when a node has child nodes. When a node is collapsed, the expand button displays a ‘plus’ sign indicating that the node can be expanded by clicking the button. Once a node has been expanded, the button displays a ‘minus’ sign.
