1C-Bitrix

Good day The
task is to assemble a complex multi-level menu
1 item -> link to the filter or catalog section -> link to the filter
2 item -> link to the news.list section
3 item is just a link
4 item -> about the company and static pages of the section
How to collect it?

Answer 1

How often does this menu change? If at all it makes sense to generate it?
The simplest solution is to hang it on statics, I mean the standard component of a multi-level menu.

Answer 2

And what's the problem? There are menu files like .menu_type.menu.php, there are .menu_type.menu_ext.php. And it is also possible to delay the execution of the menu template and then use such horror $GLOBALS['BX_MENU_CUSTOM']->AddItem();
Lots of options. Everything is limited by your imagination and skill.
