Thank you mrina(@mrina-1) for the code.
Provide id to date field
[date* depature-date id:checkin]
Keep the below code in theme functions.php
add_action(‘wp_head’, ‘ativa_data’);
function ativa_data(){
?>
<script type=”text/javascript”>
jQuery(function() {
jQuery(“#checkin”).datepicker({
dateFormat: ‘yy/mm/dd’,
minDate: new Date()
});
});
</script>
<?php }
And it works perfectly fine.
