Select2 Dropdown Styling

I’m a technical implementation analyst who works with web environments and I’m trying to implement Select2() in a board for a searchable dropdown list.

Basically, I have a input that uses BoardScript to dynamically add search options. I wanted the ability to type in and search through results so I found Select2 after doing some searching and after following the select2 web guide, my dropdown seems to be functioning properly with search function but the styling is all off. This is what it looks like:

Alpha, Beta, Delta are my three option values. You can see that the results are displayed in two columns for some reason, which is the main issue I’m trying to fix. The search bar is also tiny. I’ve googled everywhere to try to find out how I can edit the styling of the select2 input, but I can’t find what attributes to change even after reading the official docs.

Is there any way to directly style the select2 dropdown so the results are displayed on one column? Thanks.
