Why

The core of Petri Flow is the workflow engine. However, workflow, dynamic forms, and organization systems are inseparable. Therefore, petri flow provides simple built-in dynamic form functions, but in practice dynamic forms require more complex features. Such as selecting data from other data sources, data validation, application-oriented data fields, UI customization, etc. Petri Flow abstracts the interface needed to integrate with dynamic forms, in order to integrate more complex dynamic forms systems, such as form core.
