adding custom expandable side menu

Hello there,

I need to add an additional expandable side menu to some of my pages. Each page with a different custom menu.

I tried using this plugin. It is exactly what I need. The only problem is that I can add it through the widget areas only. and each widget area could hold 1 different menu. I need to add about 100 different menus and this couldn’t be done with the available areas.

I tried adding a custom widget area but was confused on how to use it!

I tried downloading a menu with html – javascript and css code files. But couldn’t integrate it with wordpress.

I tried some of the plugins that include external html file into the page, but the output was static and not the same as when you run the html file of the menu.

Can you please help?!

Thanks in advance!
