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 Some 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="chzn-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.
