});
</script>

Output


 

3. Customization

Here, are some options to customize the default behaviour –

  • Change width

Use width option to change element width. In the above example, I used it.

Example

$('select').chosen({ width: "200px" });
  • Hide search on single select element

The disable_search_threshold option hides the search box when the <select> element have less option than specified n value.

Example

Here, set the option value to 10 means search box not visible if total <option> is less than 10.

$('select').chosen({disable_search_threshold: 10});
  • Default Text

Specify your default text in data-placeholder attribute.

<select data-placeholder="Choose programming language" style="width:200px;" multiple >

To set default text on single option <select> add an empty <option> and specify data-placeholder.

  • Change no result found text

Set new value using no_results_text option.

$('select').chosen({no_results_text:"Not found"});
  • Limit selected options in Multiselect

Define max_selected_options to limit the user from selecting the maximum number of options.

$('select').chosen({max_selected_options:2});
  • Allow Deselect on Single Selects

Set allow_single_deselect: true.

$('select').chosen({allow_single_deselect:true});

NOTE – This will only works if first option is empty.


Demo


 

4. Destroy

Pass "destroy" value in chosen() method to get back <select> element to its native form.

$('select').chosen('destroy');

 

5. Conclusion

The plugin works well on desktop and it supports all modern browsers – Firefox, Chrome, Safari and IE9. Also enabled on IE8.

It doesn’t work on mobile devices the select element revert back to its native form.
