[flexcoders] Group Header Combox Dropdown List

[Jack @ Zingit]

I need to be able to have a Group Header Label for items in a dropdown 
list of a ComboBox.

These Group labels will not be selectable.  I would like to make them
bold so they will stand out.

See example(s) below.

        Group I         Project 1
           Item 1          Task 1
           Item 2          Task 2
           Item 3          Task 3
        Group 2 Project 2
           Item 1          Task 1
           Item 2          Task 2
        Group 3 Project 3
           Item 1          Task 1
           Item 2          Task 2

The Group Name label will not be the same for every ComboBox.

I could have sworn that in the past month there was a post on flexcoders
regarding something like this, but I can not find it.

Maybe I was dreaming.

Can anyone direct me to that post or any code example that does this.

Any help is appreciated.

Thanks,

Jack
