Multi Select Box Element allows the selection of multiple items with auto-complete behaviour. 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. Configuration of this element is the same with the Select box.
