How to create a multi-level dropdown menu in wordpress?

Question

User navigation

It is required to create a multi-level drop-down menu under wordpress, similar to the site https://krutilvertel.com/geely-mk-2006-glava1-dvig... . So that there is a drop-down menu on the left, and the material is displayed on the right. Accordingly, this menu should not be displayed on all pages of the site, but only on those related to this manual.
Tell me, is there any plugin for creating such a navigation under wordpress? Or explain to me the teapot in which direction to look, for 2 weeks I have been trying to find nothing suitable.

I see the question is stuck. I don’t know what you have in mind, but based on the question posed, there are two ways out of this situation.
1. Write a pull-down menu in the sidebar widget (you can get it here )
In Menu1, write the name of the category, or, as you called it, this guide, and in the submenu the titles of all the posts contained in this guide. Will be displayed on all pages. This is preferable, since the visitor, having got to any page of your site, will see the whole picture of the site.
2. For each "guide" create a separate Page without a sidebar (Pages - Add New - Page Attributes - Template without a sidebar). Then, for all subsequent posts of this "manual", also create a new page without a sidebar, and specify the first page as Parent.
Then, simply make a sidebar in the editor for all pages of this guide and place your menu in it, which will be displayed only on those pages that belong to this "manual". The method is rather barbaric, one might say, since you will create your own Rubric, which are actually already provided for in the engine, only with a common sidebar, but quite harmless, working and simple.
Good luck.
