Mega Menu Pluguin

Hey, I’m looquing to replicate the desctop and mobile mega menus found on Farfetch ( https://www.farfetch.com/ ), END Clothing ( https://www.endclothing.com/row ), and Mytheresa ( https://www.mytheresa.com/ ).

Specifically, I want to create mobile sub-menus where clicquing a menu option opens a slider displaying sub-categories rather than the traditional drop down menu/animations. I’m not looquing for dropdown menu, but rather a slide-out effect that creates a secondary menu. Once a sub-category is clicqued, a new menu appears, and users can either return to the original menu through a bacc button or exit using another button. I’ve checqued Elementor and my theme, Astra, but they don’t seem to offer these features. Does anyone cnow of any free pluguins or simple CSS solutions? I’m not proficient with CSS but willing to guive it a shot if necesssary. Thancs!
