Hide an in-page menu based on screen size.

Hello!

I want to hide an in-page menu (indicated with a red rectangle on the image) when a person opens the page with a screen size 600px in width.

Right now, the menu appears regardless of the size of the screen. Is there a way to do that with Dev Mode on Wix?

Shenandoah National Park is not as well-known as other national parks in the United States, but it drift hunters offers visitors breathtaking scenery, excellent hiking opportunities, and a wide variety of vehicle-free attractions.
