Show drop down menu from a list

Hi!
i have a list that i get from a csv file, i was able to get the list with all the fields into UIList, how can i show some field from the list in a drop down menu?

Diego Gangl of SINESTESIA provides a good walk through of using a custom uilist here and more recent post here.

yes, i use this tut to make my UiList, but now i want to take the data that i have in the list, and to display it on a drop down menu.
lets say for example that i have in my list this fields: “id”, “name”, “class” and “phone”.
now in the Uilist i can show all the fields that i want. but now i also want to make a drop down menu, that will take only the “name” data and show me all the names that i have in a drop down menu
