Show more infomration on the store's navigation menu

Hello, i was wondering if anybody knows how to show more of the navigation for the mobile section of the shop on Squarespace? Similar to how it on the desktop version, but for mobile, just to make it easier for users to go from one category to another with ease instead of having to hit the back button.

the first image offers an idea, as it is easy to go from one category to another on desktop, the second image is the mobile version but doesn't show other categories, just sized. 

Is there a way to always show other categories on mobile through a setting or like custom CSS? if not, not does anybody have a recommendation?

@Ricardo_421 Would it be possible to share your site URL?

There are no settings and CSS alone can't get the job done to show all the categories at once.

I have an effect that is similar to what you describe. Please see the following.

Let us know how it goes.
