React menu best practices

I'm fairly new to React, and I'm building out a dropdown navigation menu that toggles on hover. I need to know what best practices would be for toggling this menu.

Currently I'm using state to toggle a data attribute that I can reference in the CSS ie data-menu="open" for the mobile menu. Should I be doing it this way, or should I use state to toggle the menu open and closed?

Thanks in advance, I'd love anyone's input here.

You don't need to use react for that you could just use an :hover css selector
