I don’t know if a topic already exists, but couldn’t find it with search.
For normal fields it’s possible to give them a width of 50% to get them aligned next to each other. For Flexible subfields this does not work (even though the width field is available). Would be awesome to get this to work for flexible fields as well.
Due to the fact that the width field is present in flexible subfields already this could be a bug as well (?).
