How to disable options in select2

jquery, jquery-select2

Solution

you can reinitialize select after disabling it use following code

$("select").select2("destroy").select2();

something like

$('select[name*="pref"]').change(function(){

    // start by setting everything to enabled
    $('select[name*="pref"] option').prop('disabled',false);

    // loop each select and set the selected value to disabled in all other selects
    $('select[name*="pref"]').each(function(){ 
        var $this = $(this);
        $('select[name*="pref"]').not($this).find('option').each(function(){
           if($(this).attr('value') == $this.val()){            
               $(this).prop('disabled',true);               
           }
        });
    });
    $('select[name*="pref"]').select2("destroy").select2();
});

hope i am getting you right
