I have read several threads regarding this issue and voted in the issue tracker for this same issue. Are there any plans or fixes to allow a user to search in a combo box and get a filtered list with checkboxes? Adding the checkbox manually and then managing all the code to make it look like the built-in functionality is clunky and just doesn't look as professional as what Telerik has created. This sure would be a nice enhancement of the radComboBox control.
