Once you have downloaded the menu files and unzipped them you have to copy/load them into your web files so they have an address pertinent to your site.
Then you have to copy the script code at the bottom of the page at milonic.co.uk where your menu is.
Paste that into the body of the page you want the menu in.
Underneath that type <script language="JavaScript" src="
http://www.yourwebsite/mmenu_array.js" type="text/javascript">
</script><script language="JavaScript" src="
http://www.yourwebsite/mmenu.js" type="text/javascript">
</script>
Change "yourwebsite" to the name of your website and make sure the address and name of the .js files are the same as yours.
I can't see the menu in my edit page, but it works fine on the browser. I'm now trying to customise it. Hard graft. They don't make it easy do they!
Hope this helps.
Of all the things that I have lost, I miss my mind the most.
