How can I create a hover menu for my refresh theme?

[anpanman]

Hi Shopify community,

Here is my site:

standouthairco.com

I want my menu for texture and style to hover, giving the user immediate view on all possibilities without having to click twice. You can use https://shop.luvmehair.com/collections/human-hair-wig as a reference.

Can someone provide the css code for this? 

Thank you!
