Spell checking not working in Portable Text Editor (PTE) in Sanity v2.27

You're right that spellchecking should work in the Portable Text Editor - and it does support it! The issue you're experiencing in Sanity Studio v2.27 is likely because spellcheck needs to be explicitly enabled in your schema configuration.

The Portable Text Editor does support spellchecking through the spellCheck option on the block type. While this option defaults to true, there have been cases in Studio v2 where it needs to be explicitly set to work properly.

Here's how to fix it - add the spellCheck option to your block type's options object:

{
  title: 'Content',
  name: 'content',
  type: 'array',
  of: [
    {
      type: 'block',
      options: {
        spellCheck: true
      }
    }
  ]
}

The key is placing spellCheck: true inside the options object at the block type level. This is a Boolean option that explicitly enables spellchecking in the Portable Text Editor.

After updating your schema with this configuration, restart your Studio development server. The spellcheck functionality should then work in your Portable Text fields just like it does in your regular text fields.

If you're still experiencing issues after adding this, double-check that:

• The option is nested correctly within the options object
• Your browser's spellcheck isn't disabled globally
• You've fully restarted the Studio (not just refreshed the page)

This should resolve the spellcheck issue you're seeing in Studio v2.27's Portable Text Editor.
