Responsive dashboard

Hi!
Maybe someone can give me some advice.

I have a website that has different dashboards for different users. For making the menu at one side like a tipical dashboard I used the “fix feature”. The problem: now the site have problem when is displayed in differente screens. Is there a way to fix this? Or to make it somehow more responsive?

Obviously the page will be displayed differently when viewed on different devices like desktop, tablet and mobile devices.

If you have setup your Wix Editor and it all looks fine in the Desktop Editor, then go to your Wix Editor and the Mobile Editor and change the pages that you want to have it shown and not just how Wix automatically applies it for mobile versions.
