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
