ACF-like dynamic field manager for Node.js + MongoDB

const mongoose = require("mongoose");
const FieldSchema = new mongoose.Schema({
  name: String,
  label: String,
  type: String, // text, select, repeater, etc.
  options: [String], // for select, checkbox, radio
  required: Boolean,
  defaultValue: mongoose.Schema.Types.Mixed,
  repeaterFields: [this], // will throw error
}, { _id: false }); // optional: no _id for embedded

// FIX: Use function reference
FieldSchema.add({
  repeaterFields: [FieldSchema] // recursion
});

const FieldGroupSchema = new mongoose.Schema({
  title: String,
  location: String, // e.g., "post", "product"
  rules: [{ key: String, value: String }],
  fields: [FieldSchema],
}, { timestamps: true });

module.exports = mongoose.model("FieldGroup", FieldGroupSchema);
