Dropdown menus #dropdown

I want to be able to arrange the items in a dropdown menu

The UI for multi-select from drop downs is so poor that it is prohibitive (it has to be reopened after each single selection). Why in the world would you not be able to multi-select?

Related to the above, allow options to require a user in a form to either single-select or multi-select

Hi Anthony. Command-Click (on a Mac) to multi-select.
