# Responsive Horizontal-to-Scrollable Menu

This example shows how you can build upon Pure menu classes such as pure-menu-horizontal and pure-menu-scrollable. At wide window-widths we display a horizontal menu. At smaller window-widths, we switch to a scrollable horizontal menu with a toggle control. Remember that the JavaScript provided is plain vanilla JS so it won't work in some browsers; you'll need to polyfill or adapt the code to your library of choice.

Code reproduced below:

    <style>
          .custom-menu-wrapper {
              background-color: #808080;
              margin-bottom: 2.5em;
              white-space: nowrap;
              position: relative;
          }

          .custom-menu {
              display: inline-block;
