Menu issues

So the default customizr top menu looks bad when viewed on tablet or phone. I also created a sidebar menu which basically doesnt expand or collapse. It just stays expanded. When browser size reduced to tablet, it goes all awry.

I any case, i found another menu plugin mega max menu and tried it. It works great. Except, i need to move it above the slide a bit which I did, but the sublevels look off after doing that. Also in responsive mode, on the laptop, the drop down doesnt show up but it does show on the tablet and phone.

Also there is no vertical option unless I use a jscript plugin.

Can I remove the customizr menu somehow so that it doesn’t interfere with the mega max menu. I found a code but that removes the whole menu in general.
