ColorListDropDown Component
The PureComponents ColorListDropDown control is used to display data in a drop-down combo box. By default, the ColorListDropDown control appears in two parts: the top part is a text box that allows the user to type a list item. The second part is a ColorList that displays a list of items from which the user can select one.

ColorListDropDown is based on a ColorList component therefore the interface is similar. The differences are described here, the common information can be found in the ColorList chapter.
Popup window has a header at the top which can be turned on and off with the ShowHeader property. The ShowStatus property shows and hides the status bar at the bottom. The text is accessible through HeaderText and StatusText properties. By setting the AllowListResize property to true you can allow the user to resize the popup window.
