There are two ways:
1) In the Layout Designer right click and select 'User Class'. You get an empty ctrl that you can layout and you can then set the class type using the panel on the bottom left (eg. to ColumnList).
2) To add a control to the Layout Designer menu and have a preview available while laying out you can create a .usc file in your package and add a script for it. See CtrlLib/CtrlLib.usc for examples.
