Attaching a drop-down box within a view(not toolbar)

I have a view (NewDeploymentView) that looks like this

Name:________________
Build:_________________
Servers++++++++++++++

The name and build text box work fine but i want to have the server "text box" be a drop down list of all available Servers(a seperate ArrayList of <object> type Servers in the TreeViewer). So it needs to be able to interact and refresh the choices if a server is added or deleted to the Servers node.

Would this be a JFace component or Swing or what? I don't even need code if someone can point me in the right direction of what I'm actually supposed to be searching for I'd greatly appreciate it.

Nevermind found it. Just have to see how to grab the List instead of pre-defined strings
