# ComboBox
The <xref:System.Windows.Controls.ComboBox> control presents users with a list of options. The list is shown and hidden as the control expands and collapses. In its default state, the list is collapsed, displaying only one choice. The user clicks a button to see the complete list of options.
The following illustration shows a <xref:System.Windows.Controls.ComboBox> in different states.
