I want to customize fields like this layout.

I have added section by customizing form, but I want section without separator line.

I want to keep it visualised like a single section.

Is this for the print format or form view. In Print format you can turn on/off line breaks by clicking on “Edit Properties” in your custom print format.

It is for Form view.
