Solved How to change animation of submenu

Hi all, I have this freaky animation while opening sub menu ie. "oferta": e-superoptyk.pl. I want to make this animation more gentle and simple. I was looking for place in divi theme to custom it but failed. On the internet I found a way to change it but only with custom css.

Is there any way to simply choose default, simpler animation of submenu in divi theme / builder? Or do I have to use custom css to overwrite it?

 

Oh Guys, I've solved it myself
For those whose like me who are new in Divi there is a option for that in Theme Customizer
