How can I show in search engine to choose only from the main categories and not from all available? https://i.snipboard.io/C8UcBQ.jpg Because there are a lot of categories, and it’s hard to scroll through the whole list.
I saw the screenshot you attached. Sorry but there is no option available for that.
You can try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS. This will hide sub-categories from the search dropdown.
