I need a page where i have a listbox and a combobox filled with choices.  
There will be a link called “Add” that will add the selection in the  
combobox to the listbox. Then when the page is submitted, the controller  
collects the items in the listbox.

I have tried fiddling with collect\_select and select, but did not get  
far.

Any help is appreciated!
