Hi! I'm trying to create a multilevel form with a repeater pattern, and I’m wondering if that’s possible. For example, I’d like to create a form where users can add new rows dynamically, like this: 
We also have sections like this, where each section can contain multiple rows, with an “Add new line” button similar to the screenshot. Is there a good way to structure this with the builder library? Thanks! |

@sn4h did you try using an entity of type group maybe and children of type row with relation constraints ? |

@sn4h It is indeed possible. Here's a live example I implemented for your use case: The idea is that you can define multiple builders, nest them within each other, and recursively chain their validations. Feel free to take a look at the code and let me know if you need any help. |

The example includes a
mainbuilder used to createsectionandtableentities, and atablebuilder whose schema is stored in thecolumnsattribute oftableentities.Feel free to take a look at the code and let me know if you need any help.
