jQuery UI Datepicker.  
Description and examples: http://jqueryui.com/datepicker.   
This input is also accessible as **date** type. Do not use it together with __bootstrap-datepicker__ as both apply <code>$().datepicker()</code> method.  
For **i18n** you should include js file from here: https://github.com/jquery/jquery-ui/tree/master/ui/i18n.

@class dateui
@extends abstractinput
@final
@example
<a href="#" id="dob" data-type="date" data-pk="1" data-url="/post" data-title="Select date">15/05/1984</a>
<script>
$(function(){
    $('#dob').editable({
        format: 'yyyy-mm-dd',    
        viewformat: 'dd/mm/yyyy',    
        datepicker: {
                firstDay: 1
           }
