Jump list menu

I am looking for a way to set up a jump list menu on a page. The page has 30 products on it so there is a lot of scrolling up and down. I want to have a simple drop down menu on the page like this website…….https://0373493.netsolhost.com/rhch/

I want the links to go to an anchor on the same page. The menu would list all the products on the page and link to each product on the page.

Here is the website page that I am working on……..https://thielen.technicalwritinggroup.com/attachments/skid-loader-attachments/
