Can't use Jquery UI in Laravel Boilerplate (date picker)

 Solution:

Put jquery ui library file after manifest.js

Do you want to find the issue please comment all js library files except jquery.

then put this code for check UI loaded

<script>
    $(document).ready(function() {
        if (jQuery.ui) {
            alert("loaded");
        }else
        {
            alert("not loaded");
        }

})
</script>

 then check and uncomment commented libraries one by one

simple Jquery in progress image

//start function
function  update_consignement_in_details() {

  $('#msg_div').html('<img width="20" height="20" src="'+CI.base_url+'images/b_loading.gif">');
  $('#msg_div').show();

  //function content


  $('#msg_div').css("color", "green"); 

  $('#msg_div').html('Cosignment-In updated successfully');
}
