For situations where you want to allow users just to enable or disable some options, you can consider the switcher field, which allows only two values - **true** or **false**:

```json
{
    "name": "lazyLoad",
    "label": "Lazyload",
    "group": "Additional",
    "note": "Enables lazyloading images that are currently not viewed, thus saving bandwidth.",
    "value": true,
    "type": "checkbox"
}
```

The switcher fields are great for handling the conditional displays of other options with the use of the **dependencies** parameter described under [Theme Settings API](#INTERNAL_LINK#/post/108).
