JQuery UI Menu Scroll

I'm using the native jquery ui menu and trying to get it to scroll. I found that it actually has this behavior built in (sort of). I'm not sure if it's intentional or not. JSFidd

Solution 1:

Here is scrolling on the side, no js here though obviously

 #menu {
          overflow-y: scroll;
          overflow-x: hidden;
          height: 200px;
          width: 200px;
        } 

  <ul id="menu">
        <li><a href="#">Item 1</a></li>
        <li><a href="#">Item 2</a></li>
        <li><a href="#">Item 3</a></li>
        <li><a href="#">Item 4</a></li>
        <li><a href="#">Item 5</a></li>
        <li><a href="#">Item 6</a></li>
        <li><a href="#">Item 7</a></li>
        <li><a href="#">Item 8</a></li>
        <li><a href="#">Item 9</a></li>
        <li><a href="#">Item 10</a></li>
        <li><a href="#">Item 11</a></li>
        <li><a href="#">Item 12</a></li>
        <li><a href="#">Item 13</a></li>
        <li><a href="#">Item 14</a></li>
        <li><a href="#">Item 15</a></li>
        <li><a href="#">Item 16</a></li>
        <li><a href="#">Item 17</a></li>
        <li><a href="#">Item 18</a></li>
        <li><a href="#">Item 19</a></li>
        <li><a href="#">Item 20</a></li>
        <li><a href="#">Item 21</a></li>
        <li><a href="#">Item 22</a></li>
    </ul>
