Customizr Theme Custom Menu for pages

Hello,

Im using Customizr Theme (by Nikeo, Version: 3.4.20) on my localhost website. If for an example I will make a page called “Products” I want to have a menu on the page “Products”, which would be on the left side of the site. Is this do-able? I would like it to be vertical menu. I would like to have it also as like “drop-down”. So for a example if I would have put page to the menu called “Door”, then If I would click on the “Door” page, I would be able to put something as a sub-item to that “Door” item on the menu.

Thank you for your help.
