TIWCGJQDropDownOptions.Placeholder Property
Initial value that is selected if no other selection is made.
The placeholder can also be specified as a data-placeholder attribute on the select or input element that Select2 is attached to.
Note that because browsers assume the first option element is selected in non-multi-value select boxes an empty first option element must be provided (<option></option>) for the placeholder to work.
