I would like to reduce columns in configurable list but I can't seem to adjust (see below)?

Would like to the mirror format in the configurable list that has been established in the matrix where names are provided.  Problem is setting column with in radio selections and I would also like to center # above radio button.

I'm not sure if I understand your query correctly. Do you mean to increase the width of the radio buttons in the configurable list widget and center the number displayed on the header row or decrease the width of text box?

We may adjust the width of the cells by injecting custom CSS to the JotForm. If you can provide us with more information on what exactly that you are looking for, so that we can provide you with necessary assistance.

We will wait for your response. Thank you!
