 * A toggle panel is an item which can hold other items. The difference between
 * a grid and a panel is that it's possible to define how a panel looks. A grid
 * in an invisible container to just hold the items. The toggle panel is a
 * combination of the panel and a toggle button, it allows a toggle button with
 * its own grid.
