2. Is it possible to reduce the spacing between the supply & fit, supply only and fit only options in the horizontal direction?

Hi,

Yes that's possible by injecting custom CSS codes to your form. You can use the following CSS for your form.

#id_7 .form-multiple-column .form-checkbox-item {

width: 100px;

}

100px width would give you like the following. However, you can change 100px to something you prefer.

Hope this helps!
