The current repeatable field uses the table layout for form input display.
Nice to display a "typical" data table with headings. It works quite well for a smaller amount of fields and fields that do not require too much space itself. There is also some sort of "responsive" table display through CSS and media-queries...: Columns begin to stack vertically.

But with larger fields like editor or media, it can easily break the layout. Not to mention a greater amount of fields.

The core XML subform field seem to supply different layouts. Excerpt from documentation...

joomla.form.field.subform.default
render the subform in a div container, without support of repeating. Default for single mode.
joomla.form.field.subform.repeatable
render the subform in a div container, used for multiple mode. Support groupByFieldset.
joomla.form.field.subform.repeatable-table
render the subform as a table, used for multiple mode. Supports groupByFieldset. By default each field is rendered as a table column, but if groupByFieldset=true then each fieldset is rendered as a table column.

The 2nd "repeatable" layout is based on DIV's. It always stacks the sub-fields vertically. It has also a different button layout and positions. The DIV layout is always top-to-bottom. It works well on any screen-size.

Currently you can't switch to this or any other layout, because the table based one is a hard-coded default.

Describe the solution you'd like

A parameter to choose the form input layout.

Maybe a toggle between the 2 multiple mode layouts is enough in this particular case?
Although a dynamic layout select box is probably more versatile and future proof.

Thanks in advance!
