Introduction
The Multi Select Box allows you to select multiple items with auto-complete behavior. Multi Select Box is a useful replacement for the ordinary Select Box, particularly when there is a very long list of options to choose from. Options are displayed based on the user's input.
The Advanced Grid is only available on Professional and Enterprise Edition.
