  Traditionally, a ToolBar holds Buttons but a WPF-ToolBar can hold any sort of WPF elements. However, the ToolBar changes the appearance and behavior of most of its elements in order to give them a common look and feel.
If a ToolBar has more content than it can fit in window, it places the invisible elements in an overflow menu, which can be seen by clicking the drop-down arrow at the left (or lower) end of the ToolBar.

The image shows a horizontal ToolBar of 4 Buttons, 3 CheckBoxes and a ComboBox.
