A ComboBox component allows a user to make a single selection from a drop-down list. A ComboBox can be static or editable. An editable ComboBox allows a user to enter text directly into the text field at the top of the list. If the drop-down list hits the bottom of the document, it opens up instead of down. The ComboBox is made up of three subcomponents: the BaseButton, TextInput, and List components.
In an editable ComboBox, only the button is the hit area--not the text box. For a static ComboBox, the button and the text box constitute the hit area. The hit area responds by opening or closing the drop-down list.
When the user makes a selection in the list, either with the mouse or through the keyboard, the label of the selection is copied to the text field at the top of the ComboBox.
