Dropdown Arrow Side Bar

How would I remove the sidebar arrow from the dropdown box? I find it a bit unsightly, but can’t find an option for it in Edit?

You can’t really, we use the native component of the browser for this, and I don’t think they offer any option to remove (tell me if I’m wrong).

I guess the side bar arrow on a repeating box is the same way. For example if I had room for 10 boxes on a repeating container and did not want the sidebar arrow to show up until more than ten boxes had information in them.
