Create a vertical navigation drawer

I am trying to get add a navigation drawer to come from top to middle (see attachment), and that is triggered by multiple buttons or links in the content area.
Is it possible to trigger a hidden section to show or is there another way around it?
The picture explains better.
Thank you in advance.

Hi,

Thanks for writing in! Regretfully this isn’t a feature offered by X. It could be possible with custom development, but this would be outside the scope of support we can offer. You may wish to consult a developer to assist you with this. X is quite extensible with child themes, so there are plenty of possibilities.

Thanks for understanding. Take care!
