What I want to be able to do is either enter a new value to be acted on or make selections ( sometimes multiple selections ) from previous entries... an entry widget with a button, and a listbox that drops down when the button is selected... I have a widget that uses a button to expose a listbox in a toplevel and now I need to make history entries as well as multiple selections. HLists won't work. thank you for taking the time and lending your expertise.
