I have implemented a multi-select drop-down menu in the snippet below. It seems to work fine. However, each time I select an item, the menu closes. I'd like the menu to stay open until the User clicks a 'done' button.
Strangely enough, the menu stays open if I deselect an item, but closes if I selected an item.
