# Form Modes

Joyfill forms can operate in two modes that control whether users can edit fields.

### **Available Modes**

```kotlin theme={null}
enum class Mode {
    fill, readonly
}
```

### **Setting the Mode**

Set the mode when creating your Form:

```kotlin theme={null}
Form(
    editor = rememberDocumentEditor(json),
    mode = Mode.readonly  // default is Mode.fill
)
```

### **Mode Comparison**
