Smart multi-row is a new addition to ConfiForms field types and "smart fields" family in particular.  This field type enables you to create master-details forms much easier than before.

It has been introduced as beta in 2.21.1 - Release Notes#Version2.21.1 and as GA in version 2.24.7 - Release Notes#Version2.24.7

As with all the "smart" fields in ConfiForms this field is about linking forms together, but with one important difference - it allows you to ADD new records into the referenced form directly and in "one go"

Here is what we mean

Consider a simple form with 2 fields named "participantsForm"

• Name (text)
• Mark (numeric)

And another form that we want to use as a database to store our tests - "testsForm"
