PrestaShop 1.7.6.8 - Theme Classic - Top Menu - Limit Category Levels to Show - FIXED

[PrestAlec]

Hello!
In the Top Menu I needed to limit the Categories detail level to 1, and I found solutions only for prior versions of my PrestaShop version.
I'm no expert coder at all, so please be kind... may be I performed major surgery instead being a bit more gentle 🙃
