Add a horizontal menu at the top

Hello, we are currently using xwiki 12.10.7. Please tell me how you can add a horizontal menu at the top. I want to set it up as shown in the example on Screen_1. At the moment we have the following Screen_2.
I can’t find the settings that are responsible for this in the xwiki administration, please tell me how you can make such a menu?

Screen_2

See https://extensions.xwiki.org/xwiki/bin/view/Extension/Menu%20Application . Note: This is an extension that is installed by default in your wiki.

Hello, yes, I have this extension installed (Screen 1), but when I go to the settings: Global Administration: Menus, I see a blank page there (Screen 2). Please tell me why nothing is displayed there?

hmm why don’t you follow the instructions on https://extensions.xwiki.org/xwiki/bin/view/Extension/Menu%20Application ?

not sure about that but you shouldn’t need to go there. How did you access it?

In any case just follow the instructions at https://extensions.xwiki.org/xwiki/bin/view/Extension/Menu%20Application

After reinstalling the Menu Application extension, it became possible to add entries in Administration: Menus. Before reinstallation, it was empty. After that, it turned out to create a horizontal menu. Thanks.
