jquery chosen, empty String as option
You can also set *allow_single_deselect* to true. This will have a 'x' that allows user to deselect the option.
$(".chzn-select").chosen({ allow_single_deselect:true });
after some research i found this thread
https://github.com/harvesthq/chosen/issues/93
and my solution was prepending an option via JS before initialisation of chosen
$("#id").prepend("<option value='' > </option>");
So this one is Resolved, thanks to and everyone who had a look at this
