[Theme: Hadron] Menu Distortion when zooming

Hey!

First of all, thank you for your time and help.

I have a small problem with my website: https://www.darrylsyms.co.uk in that when I zoom into the page (particularly on a mobile device), the top menu will create a second column because it will no longer fit in the header. I’ve tried experimenting and I just cannot figure out how to stop this. I think what I’m asking for is how to make this menu unresponsive?

Ultimately, I think that the mobile menu for this theme is very restricting and too compact. So what I’m trying to do is amend the viewport so that on a mobile device, it just shows the desktop view. The only hurdle I can’t figure out is this menu problem!

Any suggestions or input would be greatly appreciated!

Thanks ??
