Decodes SurveyJS-compatible JSON data or maps into DynamicForm.Instance structs.
This module handles the conversion of SurveyJS-format JSON form configurations into proper Elixir structs, including nested elements and special types.
SurveyJS Format
This parser accepts SurveyJS-compatible JSON format. See: https://surveyjs.io/form-library/documentation
Examples
iex> json = ~s({"id": "my-form", "title": "My Form", "elements": []})
iex> DynamicForm.Parser.FromData.parse!(json)
%DynamicForm.Instance{id: "my-form", title: "My Form", elements: []}
iex> map = %{"id" => "my-form", "title" => "My Form", "elements" => []}
iex> DynamicForm.Parser.FromData.parse!(map)
%DynamicForm.Instance{id: "my-form", title: "My Form", elements: []}Summary

Decodes a DateTime from an ISO8601 string.
Decodes a single element based on its type.
SurveyJS uses type to distinguish between question types and element types.
Decodes a list of elements (questions and panels).
Decodes a panel or HTML element map into an Instance.Element struct.
Decodes a question map into an Instance.Question struct.
Decodes a single validator map into an Instance.Validator struct.
Decodes a validator list.
Parses a JSON string or map into a DynamicForm.Instance struct.
Supports SurveyJS format with pages array or flat elements array.
An already-parsed %DynamicForm.Instance{} passes through unchanged.
