Modal Window Question

In my application, there is a popup that contains a list. I have a button that displays a modal window to add additional items to the list. But the popup disappears when I would like it to stay visible before and after the user completes the modal window to add additional data to the list.

Any suggestions how to implement this?

Thanks,
Kris
