How can I have the sub label in the file upload field not to wrap?

Also, on the 'attached file' field, how can I make it so the sub-label is all on 1 line?

Our apologies. The container of the button is limited to 200+ width only which is causing the labels to wrap automatically. I have fixed that for you by overriding the label width with a fixed value below:

label#label_pleaseAttach45, label#label_pleaseAttach {

    width: 500px;

}

You can check the custom CSS codes in the, guide: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes.

Great! Thanks
