Hover animation in the header.

[CreatorTim]

Hey guys, I need help with a hover animation in the header.

I’d like a smooth sliding animation for the submenu. So, when I hover over the menu item "Products," the submenu should slide out smoothly every time.

I want the same animation as here when you hover over "store": https://tomnoske.store/

And here’s my store: https://1049xn-ya.myshopify.com/

Thanks for your help,
Tim

	block-size: 0;
	overflow: hidden;
	transition-property: block-size, content-visibility;
	transition-duration: 0.3s;
	transition-behavior: allow-discrete;

	block-size: calc-size(auto, size);
}
