[Beginner] Stuck with off-canvas and button to toggle menu

Hi everyone (first post),

Sorry for the beginner question (I started foundation less than 24 hours ago …). I got most of the desired design for my website, except for the off-canvas vertical-menu. The menu itself works perfectly (off for small and medium, and on for large). However, I can’t succeed with having a (working) toggle button for the menu. The button should appear only for small and medium.
I have tried the examples in the doc without success.

Here is my working example without the toggle button mentioned above. Any tip?

I see no $(document).foundation() in your code. Did you miss the part to initialize Foundation Sites?

Can you provide a working codepen with yout code?
We have visibility helper classes. See https://get.foundation/sites/docs/visibility.html

Thanks for the quick reply.

I just hit the Download button on the foundation website, that provided me with a zip containing an index file (without $(document).foundation()) and an asset folder the CSS and js files.
Is it critical? (I will try to look a bit more at the installation part)

As it is my first site for a decade, I was not planning to use SASS, node, or other recent tools unless I need it before understanding Foundation and recent HTML/CSS.

I was not aware of CodePen, it is really, here it goes: https://codepen.io/azzaare/pen/XWmONqr

Thank you for the link for the visibility helper classes. I will check it asap.

I guess you downloaded the complete setup from https://download.get.foundation/sites/download.

This is not needed, please see the CDN files that you can download and host yourself:

Thank you for your answer. I am sorry to come back to you so late (things are a bit chaotic with the covid …)
I think I downloaded that version: https://static.download.foundation/sites-css-latest

I will try to work with some examples on the web till I get what I am doing wrong (probably related to the use of JS). If I am still stuck, I will provide a codepen and ask again!
