There are test files for many-to-many in:
t/default_values/
t/update/
t/options_from_model/

Check the many_to_many_select* test files.
You'd need to use an element for which multi_value() is true, e.g.
Select or Checkboxgroup

I don't think it's currently possible in a single step, to both select
which one's to relate, and edit them.
It's either a multi-value element to select them, or a Repeatable
block to edit the already related rows.
