How do you reset a Chosen multiple select field using jQuery?

Seems like combination of the two answers works for me:

$('.chosen-select option').prop('selected', false).trigger('chosen:updated');

This deselects all options and also resets the chosen drop down.

Try this

$('.chzn-select').val('').trigger('liszt:updated');

This worked for me:

$('form#form_id').find('select').each(function(i, element) {
    $(element).chosen('destroy');
    $(element).prop("selectedIndex", -1);
    $(element).chosen();
});
