Help with how to edit the top part of a page

Alright, I am not all that experienced with Word Press and I have a good knowledge of HTML and CSS. I need help editing the top part of a website. This site was not made by me and was made by a different person who I don’t have contact with.

Just that top menu. I don’t know how to edit it. I’ve tried going to the pages menu, but It doesn’t show up. I go to Customize<Menu and nothing helps me there. This is probably really simple, but I’m needing help here.

This was done in The7 theme

Hi there

Its not our theme, you need to contact to the theme author about this :slight_smile:
