From menu to dropdown menu: Is there a risk?

[AxialDev]

Good day!
We are thinking about replacing a traditional menu on an e-commerce website with a Shop button like on Amazon, with a dropdown and expandable sub-menus.

Current menu: Category 1 | Category 2 | Category 3 | ...

New menu: Shop | Search bar

The Shop menu would expand on mouse hover. When clicked, it would link to a directory like on Amazon: https://www.amazon.ca/gp/site-directory/.

Is there anything we should be worried about (ex. link juice, engagement) or considerations to think about (CSS-based vs JS)?

Thanks for your time!

As long as you're not using JS to draw the new links (i.e. CSS hides them until an appropriate hover event) you should be just fine. Google will still spider the links from the source code.
