==============
FlexForm field
==============

Renders a :ref:`FlexForm <t3coreapi:flexforms>` element. Essentially, this consists in a
hierarchically organized set of fields which will have their values saved into a
single field in the database, stored as XML.

The general idea is: There is a data structure that defines which and how single
fields should be displayed, re-using all the TCA column type possibilities. The
actual values of single fields are then stored in an XML representation within
this "flex" field.
