title: Enabling a date-picker in Woocommerce checkout fields
body: <p>I'm trying to change checkout fields in woocomerce, from addres1 and addres2 to checkin, and checkout. I would like to use Datepiker on those two fields. This is an extract of my <code>WC_Countries</code> Class core code that I have changed:</p>
  
  <pre><code>            'checkin'  =&gt; array(
              'id'           =&gt;'datepicker',
              'label'        =&gt; __( 'check in', 'woocommerce' ),
              'placeholder'  =&gt; __( 'check in', 'woocommerce' ),
              'required'     =&gt; false,
              'class'        =&gt; array( 'form-row-wide',),
              'autocomplete' =&gt; 'datepicker',
              'priority'     =&gt; 50,
          ),
          'checkout'  =&gt; array(
              'id'           =&gt;'datepicker',
              'placeholder'  =&gt; __( 'check out', 'woocommerce' ),
              'class'        =&gt; array( 'form-row-wide'),
              'required'     =&gt; false,
              'autocomplete' =&gt; 'datepicker',
              'priority'     =&gt; 60,
  </code></pre>
  
  <p>I have also add </p>
  
  <pre><code>    $('#sandbox-container .input-daterange').datepicker({
  });
  </code></pre>
  
  <p>To my custom.scripts.js in themes directory but it doesn't work…</p>
  
  <p>Is there any way to add <a href="https://uxsolutions.github.io/bootstrap-datepicker/?markup=range&amp;format=&amp;weekStart=&amp;startDate=&amp;endDate=&amp;startView=0&amp;minViewMode=0&amp;maxViewMode=4&amp;todayBtn=false&amp;clearBtn=false&amp;language=en&amp;orientation=auto&amp;multidate=&amp;multidateSeparator=&amp;keyboardNavigation=on&amp;forceParse=on#sandbox" rel="nofollow noreferrer">Datepicker</a> in to the checkout fields in woocommerce?</p>
