Multiple items can be retrieved with various methods:
getItems() // returns an array of all items
getSelectedItems() // returns an array all currently selected items
getUnSelectedItems() // returns an array all currently unselected items
Each item returned from these methods is stored as an object in the following format:
{
node: HTMLElement, // the element node
rect: DOMRect, // the element node's bounding box
startselected: Boolean // item was already selected on mousedown / touchstart
selected: Boolean, // item is currently selected
selecting: Boolean, // item is currently being selected
deselecting: Boolean // item is currently being deselected
}
