So you are creating this for the web right?
Check Adalo website from your phone. It has a menu with that categories.
So the rectangles and other ones are messy in the phone I think it’s because you created this bar on a web app. So that one is suitable for the web. I think you have to create a one for the Web and another one for the phone with a menu.
And you can check this component created by @Michael.
I hope this information will help you.
Thank you
