Width Multiple Choice option

I have multiple choice field.

I set column size to 3 to show 3 options in a row.

But, it expands only half size of full width. So the text is truncated.

How do I expand to use full width?

Thanks,

Please inject this custom CSS Code to your form:

.form-input {width:100%!important;}
