Prevent select dropdown default on iphone

Heyy all.
how can i prevent this ui kit from appearing on phone?

I want it to appear as I have it on desktop.

I tried to put this custom code I saw in another post but it didn’t work.

textarea, input.text, input[type="text"], input[type="button"], input[type="submit"], .input-checkbox { -webkit-appearance: none; }

You can use custom code to replace the default one with more customizable dropdown.

options would be niceselect.js or Finsweet’s custom solution
