GP Nested Forms

This add-on introduces a Nested Form field type, allowing you to embed one form within another. It is designed for site builders who need to collect structured, repeatable data—such as event registrations with multiple attendees or product orders with configurable options—without creating cumbersome, lengthy forms. The child entries are managed within a compact table on the parent form and are stored as related entries.

• Nested Form Field: Adds a dedicated field type to your form builder. You select an existing form to serve as the child form, whose entries will be attached to the parent submission.
• Repeater Functionality: Serves as a form repeater, letting users dynamically add multiple instances of the same set of fields (like adding several team members) through a modal interface.
• Data Calculations: Supports merge tags to calculate sums, totals, and counts from child entry data, enabling dynamic pricing or totals in the parent form.
• Feed Processing Control: Choose whether feeds (like email notifications or user registration) for child forms process immediately upon child entry or only after the parent form is fully submitted.
• Export and Templates: Child entries can be exported alongside parent data. A templating system allows for customizing the front-end display of nested entries and their data.
