Add Tabs to Document in Structure Builder

Yes! Sanity has a native feature called Field Groups that lets you organize document fields into tabs directly in your schema. This is the recommended way to add tabs to documents in Sanity Studio (works in both v2 and v3).

Here's how to implement it:

Basic Implementation

First, define your groups in the document schema, then assign fields to those groups:

export default defineType({
  name: 'article',
  type: 'document',
  groups: [
    {
      name: 'content',
      title: 'Content',
    },
    {
      name: 'seo',
      title: 'SEO',
    },
    {
      name: 'settings',
      title: 'Settings',
    }
  ],
  fields: [
    defineField({
      name: 'title',
      type: 'string',
      group: 'content', // Assigns this field to the content tab
    }),
    defineField({
      name: 'slug',
      type: 'slug',
      group: 'seo', // Assigns this field to the SEO tab
    }),
    defineField({
      name: 'publishedAt',
      type: 'datetime',
      group: 'settings', // Assigns this field to the settings tab
    }),
  ]
})

Key Benefits

• Native solution - Built into Sanity, no plugins needed
• Doesn't affect data structure - Groups are purely for UI organization
• Better editorial experience - Reduces clutter and helps editors focus on related fields
• Flexible - Fields without a group assignment remain accessible

Note on Structure Builder

Field Groups are defined at the schema level, not in the Structure Builder. The Structure Builder is for organizing how documents appear in the navigation/sidebar, while Field Groups organize the fields within a document's editing interface.

If you need more complex layouts, you can also check out Fieldsets for collapsible sections within a tab, or look into third-party plugins like sanity-plugin-tabs, though the native Field Groups feature is generally the best approach for most use cases.
