# Appearance

The ComboBox provides a predefined set of appearance options.

Apart from the default vision of the ComboBox, these alternative styling options enable you to configure each individual aspect of the appearance of a ComboBox.

The following example demonstrates all the available appearance options of the ComboBox in a single, configurable demo.
