MultiSelect
Overview
This sample shows the basic usage of the MultiSelect control.
ShowFilterInput: determines whether the control should display a "filter" input above the items to filter the items displayed.
CheckOnFilter: determines whether the MultiSelect should automatically select all the filtered items when the filter text changes.
When Case Sensitive Search is true, the user types are searched as case-sensitive
Delay: determines a period of time, in milliseconds, between when a keystroke occurs and when the search is performed to update the filter.
