Currently, ACF’s only elements for layouting in the strict sense are Accordions and Tabs, both of which are meant to hide their contents. If I want to, for example, arrange a lot of small input fields in a row, I have to use the group element, which is its own field and comes with its own slug. The same applies to repeaters and flex content.
I, too, think that ACF lacks elements, that merely serve to visually improve the back-end, but do not affect the field group hierarchy, and I would like to see more such elements implemented.
