      Default Text Support 
      
        Chosen automatically sets the default field text ("Choose a country...") by reading the select element's data-placeholder value. If no data-placeholder value is present, it will default to "Select an Option" or "Select Some Options" depending on whether the select is single or multiple. You can change these elements in the plugin js file as you see fit.
        <select data-placeholder="Choose a country..."  style="width:350px;" multiple class="chosen-select">
        Note:  on single selects, the first element is assumed to be selected by the browser. To take advantage of the default text support, you will need to include a blank option as the first element of your select list.
       
      No Results Text Support 
      
        Setting the "No results" search text is as easy as passing an option when you create Chosen:
        
          New Chosen($("chosen_select_field"),{no_results_text: "Oops, nothing found!"});

      Limit Selected Options in Multiselect 
      
        You can easily limit how many options can user select:
        
          new Chosen($("chosen_select_field"),{max_selected_options: 5});
        
        If you try to select another option with limit reached chosen:maxselected event is triggered:
        
          $("chosen_select_field").observe("chosen:maxselected", function(evt) { ... });
        
        
       
      Allow Deselect on Single Selects 
      
        When a single select box isn't a required field, you can set allow_single_deselect: true and Chosen will add a UI element for option deselection. This will only work if the first option has blank text.

      Right to Left Support 
      
        Chosen supports right to left select boxes too. just add "chosen-rtl" in addition to "chosen-select" to your select tags and you are good to go.

      Change / Update Events 
      
        
          
            Form Field Change 
            When working with form fields, you often want to perform some behavior after a value has been selected or deselected. Whenever a user selects a field in Chosen, it triggers a "change" event* on the original form field. That let's you do something like this:
            $("#form_field").chosen().change( … );
            Note:  Prototype doesn't offer support for triggering standard browser events. Event.simulate  is required to trigger the change event when using the Prototype version.
           
          
            Updating Chosen Dynamically 
            If you need to update the options in your select field and want Chosen to pick up the changes, you'll need to trigger the "chosen:updated" event on the field. Chosen will re-build itself based on the updated content.
            
              Event.fire($("form_field"), "chosen:updated");
             
           
         
       
      Custom Width Support 
      
        Using a custom width with Chosen is as easy as passing an option when you create Chosen:
        
          New Chosen($("chosen_select_field"),{width: "95%"});
