Including jquery UI in Wordpress

[admin]

I have tried to get jquery-ui working with wordpress with no luck. Can someone point me in the right direction? I've dug up a ton of SO resources and blogs explaining it, but so far can't get this working. However when I include the scripts directly in the page itself I can get the datepicker to function properly. I'm trying to make the table rows draggable (and eventually droppable).

Here is what I currently have-

In /themes/twentysixteen/functions.php

I followed the steps here and enqueued jquery-ui functions <a href="http://xl-websites.com/how-to-enqueue-jquery-or-jquery-ui-correctly-in-wordpress/" rel="nofollow noreferrer">Correctly enqueue jquery-ui</a>. I then added a couple of my own scripts based on the information here <a href="https://premium.wpmudev.org/blog/ad...Gg.1&amp;utm_referrer=https://www.google.com/" rel="nofollow noreferrer">Add jquery scripts</a>

<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override">

/* Used to include jquery-ui scripts
*  Taken from http://xl-websites.com/how-to-enqueue-jquery-or-jquery-ui-correctly-in-wordpress/
*
*/

function add_jquery_ui() {
        wp_enqueue_script('jquery-ui-core');
        wp_enqueue_script('jquery-ui-widget');
        wp_enqueue_script('jquery-ui-mouse');
        wp_enqueue_script('jquery-ui-accordion');
        wp_enqueue_script('jquery-ui-autocomplete');
        wp_enqueue_script('jquery-ui-slider');
        wp_enqueue_script('jquery-ui-tabs');
        wp_enqueue_script('jquery-ui-sortable');
        wp_enqueue_script('jquery-ui-draggable');
        wp_enqueue_script('jquery-ui-droppable');
        wp_enqueue_script('jquery-ui-datepicker');
        wp_enqueue_script('jquery-ui-resize');
        wp_enqueue_script('jquery-ui-dialog');
        wp_enqueue_script('jquery-ui-button');
}
add_action( 'wp_enqueue_scripts', 'add_jquery_ui' );

function custom_js() {
        wp_enqueue_script('date', get_template_directory_uri() . '/js/date.js', array('jquery'), false, true);
        wp_enqueue_script('drag', get_template_directory_uri() . '/js/drag.js', array('jquery'), false, true);
}
add_action('wp_enqueue_scripts', 'custom_js');

</div>
</div>


With those addded, I created the scripts in my js folder-

/js/drag.js

<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override">

(function() {
        $(".drag").draggable({
                helper: function(event) {
                        return $('<div class="drag-row"><table></table></div>').find('table').append($(event.target).closest('tr').clone()).end();
                },
        });
});

</div>
</div>


And /js/date.js

<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override">

( function() {
        $( "#datepicker" ).datepicker();
});

</div>
</div>


In my php page I added the date id to a calendar, and a class id to the table row as targets for the jquery scripts.

<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override">

<p>Date: <input type="text" id="datepicker"></p>

        echo "<div id='table'>";
        echo "<table class='listing'>";
                echo "<thead>";
                        echo "<tr>";
                                echo "<th><b>Course Name</b></th>";
                                echo "<th><b>Fiscal Year</b></th>";
                                echo "<th><b>Course Number</b></th>";
                                echo "<th><b>Start Date</b></th>";
                                echo "<th><b>End Date</b></th>";
                        echo "</tr>";
                echo "</thead>";
                echo "<tbody>";
                        foreach($courses as $course){
                                echo "<tr class='drag'>";
                                        echo "<td>".$course->course_name."</td>";
                                        echo "<td>".$course->fy."</td>";
                                        echo "<td>".$course->course_number."</td>";

                                        $date = $course->course_date_start;
                                        $date = strtotime($date);

                                        if ($date){
                                                echo "<td>".date("m/d/Y", $date)."</td>";
                                        } else {
                                                echo "<td></td>";
                                        }

                                        $date = $course->course_date_end;
                                        $date = strtotime($date);

                                        if ($date){
                                                echo "<td>".date("m/d/Y", $date)."</td>";
                                        } else {
                                                echo "<td></td>";                                               }
                                        echo "</tr>";
                        }
                echo "</tbody>";
        echo "</table>";

</div>

When my page loads, the scripts are all there (including jquery, I put spaces since the jquery lines are at line 350, and the jquery-ui lines are at line 500), but the ui isn't functional. Anyone have any insights?
