ComboBox with checkbox items

I would like to have a ComboBox with checkbox items, what can I use or do? I'm using Delphi 2009.

We have used the following components in our different projects:

Freeware:

• TjvCheckedComboBox from JEDI VCL
• TCheckedComboBox by Tsourinakis Antonis

Commercial:

• TcxCheckComboBox from DevExpress
