In Facebook, when composing an email, the user is shown a dropdown similar to the radComboBox Filtering feature. (see screenshot link below). When selected, the selected item has a blue wrapper with X to be able to delete a selected item easily. With the samples I've seen, you can't delete individual items. It seems that you have to start over especially if you want to delete the very first item you selected. Starting over is not ideal if you already selected a few. Any idea how to accomplish similar functionality?
Any help would be appreciated.
