Tina has many advanced features that allow the entire CMS editing experience to be customized.

## Customizing Fields

Tina allows the forms to be customized through the `ui` property. This allows a custom experience to be created for your editors. Some of the main customization features are:

- Adding [client-side validation](/docs/extending-tina/validation/) to a component so that a desired format can be enforced before saving
- Customizing the rendered [field component](/docs/extending-tina/custom-field-components/)
- Customizing the [parsing and formatting](/docs/extending-tina/format-and-parse/) of user input


## Customizing the CMS instance

The `.tina/schema.ts` config has an optional `cmsCallback` parameter that can be added to customize the CMS instance.

```diff
// .tina/schema.ts

// ...
export config = defineConfig({
  apiURL,
+ cmsCallback: (cms) => {
+   cms.sidebar.position = 'overlay'
+   return cms
+ }
})
```

The `cmsCallback` hook is primarily used for registering custom field plugins. It can also be used for altering Tina's UI, dynamically hiding the sidebar on specific pages, tapping into the CMS event bus, etc.
