		Type	Description
		AppearanceEnum	A AppearanceEnum expression that indicates the type of the border of the drop down portion of the control ( where the list/tree is displayed ), , or a color expression whose last 7 bits in the high significant byte of the value indicates the index of the skin in the Appearance collection, being displayed as list's borders. For instance, if the DropDownBorder = 0x2000000, indicates that the second skin object in the Appearance collection defines the list's border. The Client object in the skin, defines the client area of the drop down portion of the control. For instance, the list or tree, scrollbars are always displayed in the client area. The skin may contain transparent objects, and so you can define round corners for your drop down portion of the control. The normal.ebn file contains such of objects. Use the eXButton's Skin builder to view or change this file.
