I see in the "New Field" dialog that the field description "can be inserted into your forms" but I don't see any documentation on how to do it.
I tried guessing with "{composer:field_description}" inside the {composer:fields} pair, but no luck.
I should clarify that the reason I want to use field descriptions this way is to enable content editors to add some descriptive text about a field below the label. And they need to be able to do everything using the Composer interface.
I am open to alternative solutions that meet this requirement.
Thanks to anyone who can help.
