I've been looking for a good, preferably free, dropdownlist control.
- It should display a summarize the selected values in a comma seperated list.
- It should display the items as checkboxes, or be highlightable.
- The items should be able to populated from an AJAX type call.
- The only input submitted by the control should be the comma seperated list of selected values.
- List items can be added and removed using server or client side calls.
If you find anything let me know.
