Prevent a multi-select input box from deselecting all the options if the user clicks a single record
<p>Is there a way to prevent a multi-select input box from deselecting all the options if the user clicks a single record with using the <kbd>Ctrl</kbd> button? Basically they would have to click the item from the list to turn it on or off and the other values would always stay either selected or unselected unless there was a click.</p>
