[Help] Custom Code for Draggable Horitzontal Menu

I want to do exactly this, I haven’t found any tutorial to do so on webflow and I am not to proficient in custom code. Please help.

Thanks in advance.

P.D. Sometimes Webflow doesn’t feel like the future of the web if so many “simple” things have to be built from scratch… they could already be integrated into the app.
