# Load the city for dropdown options

Use the literal `city` value in `params` when a dropdown-option response must include its related city. documented API schema list and item reads load the relation when requested or when `params` is empty.

```text
GET /dropdownoptions?params=city
```

Sanitized structural example:

```json
{
  "error": false,
  "result": [
    {
      "id": 7,
      "city_id": 3,
      "name": "Example zone",
      "city": {
        "id": 3,
        "name": "Example city"
      }
    }
  ]
}
```

Use `params=city` to request the related city; a separate `city_id` query parameter is not needed for this example. The example shows the requested relation only; it is not a complete City schema.
