How to create a menu in Bitrix indicating which category the items will be taken from?

Question

1C-Bitrix

There are several pages .. About the company, Contacts, Services .. there are a lot of sub-items in the services ..
How can I create a separate menu and specify that all services and sub-items go in it?
I only found how to make a top menu with all the items, and a left menu with sub-items from the top ... But I didn’t find exactly how to take from a specific category.

Answer 1

See how the menu is arranged, you initially throw out the menu component, specify that the menu has 2 levels and bind to these levels. Turn on the connection of menu files, in the desired section create a menu of the 2nd level. That is, if you already have a second-level menu where all the elements are and it doesn’t suit you, then you just need to create a second-level menu with a different name

Answer 2

Master some simple framework (laravel, yii) and you will be happy.
