## Hide Search on Single Select

The `disable_search_threshold` option can be specified to hide the search input on single selects if there are n or fewer options.

    $(".chosen-select").chosen({disable_search_threshold: 10});

## 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:

     $(".chosen-select").chosen({no_results_text: "Oops, nothing found!"});

## Limit Selected Options in Multiselect

You can easily limit how many options the user can select:

    $(".chosen-select").chosen({max_selected_options: 5});

If you try to select another option with limit reached `chosen:maxselected` event is triggered:

     $(".chosen-select").bind("chosen:maxselected", function () { ... });

## 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.

    <select class="chosen-select chosen-rtl">

Single right to left select
Multiple right to left select

## 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( … );

- ### 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.

      $("#form_field").trigger("chosen:updated");

## Custom Width Support

Using a custom width with Chosen is as easy as passing an option when you create Chosen:

     $(".chosen-select").chosen({width: "95%"});
