Changing menu's that pop-up on header - Dawn Theme

[kitchencrafted]

Hello! Is there any way I can change how the menu’s pop-up on my header? I have been looking for an answer for quite a while, but can’t seem to find it. I’d really appreciate it if someone can help me. I will list a picture of how my menu pop-up looks now and I will upload a picture for reference of how I want it to look. Also I will provide a link & password for my website.
