Default Text Support

Chosen automatically sets the default field text ("Choose a country...") by reading the select element's title value. If no title 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 title="Choose a country..." style="width:350px;" multiple class="chzn-select">
