How to change the Sub Category text transform for 1 Main Menu Item

Hi

Client site has been using your plugin for years.
Current menu is

HOME PROMOTIONS BRANDS SALON PRODUCTS CATEGORIES FURNITURE CONTACT US

I need the items under BRANDS (sub Categories) in here to be Lower Case (1st capital letter). ONLY this one .. The sub categories in the other Main Men Items and eg for SALON PRODUCTS needs to stay in ALL Caps.

I already have coding for this below from years ago so all Sub Category text is converted to uppercase. Now the client ONLY wants the “BRANDS” sub category to be lowercase and everything else stays as is.

Current code:

mega-menu-wrap-primary #mega-menu-primary > li.mega-menu-megamenu > ul.mega-sub-menu > li.mega-menu-item > a.mega-menu-link {
color: #555;
font-family: inherit;
font-size: 16px;
text-transform: uppercase;
}

This changes all Sub Category text to Uppercase. So everything under the BRANDS, and under the SALON PRODUCTS and under FURNITURE are all uppercase.

But now I need to CHANGE this so the “BRANDS” one ONLY has Lower Case and NO uppercase.
All others stay as is.

How can I achieve ONLY 1 of them doesn’t read the code to transform to uppercase please ?

This is proving to be hard for me to achieve so if you could advise on HOW to do this please would be great.

Thanks
Kristin
