In FormLayout all my components have a caption label just above the component except for the Checkbox. So for example if I have a row with just a single Checkbox (the other column is empty or the Checkbox question spans two columns) then it's very disproportionally close to the row above. Is there a way to add a caption like the other components? In my case the Checkbox is a question whereas the caption is just a simple title of what the Checkbox represents.
