How to set choices in multiple columns?

[lulamorashi]

Hi! I'm writing an escape room game in Ink and will be uploading it to itch.io directly afterwards, so limited just to what is available in the css and main.js files. I have about seven to eight choices at some points in the game, so I would like to be able to divide the choices into two columns (every time there are 5+ options). I've tried just going into the css file and adding "columns: 2;" but all this does is move the existing list of choices over to the left, and never divides them. Please help!
