title: TinyMCE Plugins: Listboxes
body: <p>I'm writing a plugin for TinyMCE, and I want to have ListBox B dependent on what's selected in Listbox A. I can make it so the initial selection in ListBox A fills ListBox B, but I cannot make a second selection, wipe ListBox B clean, and fill ListBox B with the new items.</p>
  
  <p>I've tried using just Native ListBoxes and JQuery functions but JQuery can't find them on the page.</p>
  
  <p>Thanks!</p>
