To add a horizontal menu dropdown to the Wix site, you need to create a custom menu from buttons or text.
Then add boxes when you hover over the menu item, which will open in the right place using the code. (Text must be connected to the relevant page)
Further, through the code, you need to catch clicks on the text, and after performing actions, for example, switching to another page, the transition can be implemented through Wix-Location, or you can move the screen to the anchor.
