Since some time ago we have added a support to reference Confluence templates from ConfiForms IFTTT's and from ConfiForms Registration Control macros.
This enables you to avoid content duplication and reuse the content / layout in many places.
In version 1.19 of ConfiForms addon we have added a way to dynamically set the name of the template you want to use:
Assuming you have a dropdown field or a text field called "somefield" where a user can choose or specify the template to use when a page is to be created (with IFTTT for example)
This way we can easily create, with the same IFTTT, pages with different layouts
FROM VERSION 1.47.2
You can include the template without evaluating it's parameters.
The contents of the template (value for template name will be taken from "somefield") will not be evaluated against the current record, but will be included as-is
