Wells template: how to show sidebar nav on mobile

Greetings! It's my first post here.

I am creating a site using the Wells template.
Does anyone know how to have all sidebar menu links show on mobile devices?

Note: they display perfectly on desktop.
But on mobile, only the single word "Menu" appears.
I'm seeking to have all my menu links appear (Visualizing Stories, Reaching Audiences, etc etc)
- instead of just that one word, Menu.

Thanks in advance!!

You need to use some CSS to do this. Can you share link to your site?

If your site is trial, you can setup password & share url
