Plone Appliance with Drop-down Menu functionality for 4.3 or 5.1

I need to add a drop-down menu functionality to my Plone 4.3 or 5.1 Ubuntu 16.04 VM installation. Where to find a virtual appliance with all this loaded already?

What do you mean with virtual appliance? If you need some add-on in your Plone installation, added to your buildout configuration and rerun buildout.
