# Structure

This article describes the inner structure and organization of the elements which build the **RadFontDropDownList** control.

**RadFontDropDownList** is a derivative of [RadPopupEditor](https://www.telerik.com/products/winforms/documentation/controls/editors/popupeditor/popupeditor) and it internally uses a grouped **RadListView** with default **ViewType** set to *DetailsView*. Two columns are displayed in the pop up list - while the first column stores the font name, the second column shows a preview of the respective font.
