CustomChildCreator

[blackeye1987]

Based on my Previous thread: https://processwire.com/talk/topic/7194-templatelist-inside-module-configuration/

here is an automatic child creater if you need on creation of a parent element a bunch of Child Elements.

what also works: multiple diffrent childs on same parent

caution:

sadly what also works:

first entry:

parent_id = 47

child_id = 13

child_name = something

child_numbers = 1

second entry:

parent_id = 13

child_id = 47

...

...

this should afaik (not tested) kill your System by having a infinite Loop.

because (first entry creates a child which call second entry which would then call first entry and so on).
