Customizable Floating Menu

I need to set up a secondary, customizable floating menu to appear in selected pages only on my website to support navigation of the products I am listing. Basically what I am looking for is the same as a sticky social media floating bar, that stays outside of my theme template (using vantage premiu – boxed) area, sticking on the left side of my monitor. I need this bar to appear only on some selected pages. Here is the page www.groupprodetail.com and the sticky menus are to appear only on the https://www.groupprodetail.com/home/products/tiles/selection-12-x-12/ and other selection like the 12 x 24, 16 x 16 and so forth. This way when my costumers want to look another sizes of my products they can just click on the displayed size on the sticky side bar and go to that page without having to return to the previous page or navigate via the main menu bar. I have tried everything I could try it for the last 120hrs straight, installing basically every plugin I could find on the net related to sticky side bar and could not find a single one that would work or a way to make it work. Can some one help please?
