# Member-specific options

https://www.sanity.io/learn/course/studio-excellence/member-mastery.md

The Studio’s configuration can respond to the current member’s role, offering a more guided experience for content creation.

1. Review [Roles](https://www.sanity.io/learn/user-guides/roles) in the documentation

## Read-only and hidden fields

If members of a specific role should not be able to edit a field, but will benefit from seeing its current value, mark it as read-only by inspecting the current user's roles.

1. **Update** the `event` document type's slug field so only administrators can modify an existing slug

```typescript:apps/studio/schemaTypes/eventType.ts
defineField({
  name: 'slug',
  type: 'slug',
  group: 'details',
  options: {source: 'name'},
  validation: (rule) => rule.required().error(`Required to generate a page on the website`),
  hidden: ({document}) => !document?.name,
  readOnly: ({value, currentUser}) => {
    // Anyone can set the initial slug
    if (!value) {
      return false
    }

    const isAdmin = currentUser?.roles.some((role) => role.name === 'administrator')

    // Only admins can change the slug
    return !isAdmin
  },
}),
```

1. This will only protect the field in the Studio and not from an API request

The same function is available in the `hidden` key, so fields are not visible to specific users. 

Note that the field's **value** will still appear in the data, and an invalid field can still be hidden – potentially leading to confusion.

## Tools

1. Review [Studio Tools](https://www.sanity.io/learn/studio/studio-tools) and [Studio tools reference](https://www.sanity.io/learn/studio/tool-api-reference) in the documentation

Tools can be conditionally loaded depending on – among other variables – the current user.

Perhaps you only want Administrators to see the Vision plugin for testing GROQ queries. The code below will return a filtered list to all non-administrator role users.

1. **Update** `sanity.config.ts` so that only administrators can see the Vision tool

```typescript:apps/studio/sanity.config.ts
export default defineConfig({
  // ...all other settings
  tools: (prev, {currentUser}) => {
    const isAdmin = currentUser?.roles.some((role) => role.name === 'administrator')

    if (isAdmin) {
      return prev
    }

    return prev.filter((tool) => tool.name !== 'vision')
  },
})
```
