Unable to scroll after selecting type with array input in Sanity 3.2.6

This sounds like a known bug in older versions of Sanity Studio v3. Version 3.2.6 is quite outdated (from early 2023), and scrolling issues with array inputs were reported and fixed in subsequent releases.

The solution is to upgrade your Sanity Studio to the latest version. Here's how:

1. Upgrade using the CLI command:

   npm install sanity@latest

   or use the dedicated upgrade command:

   npx sanity upgrade

2. Check your current version after upgrading:

   npx sanity versions

The latest Sanity Studio version is now v4, which includes many improvements to array handling and overall performance, including Array Tree Editing and numerous UI bug fixes.

Before upgrading to v4, be aware:

• You'll need Node.js 20 or higher
• The good news: your Studio code works exactly as before with no changes required
• Test in a development environment first

If you want to stay on v3 (not recommended long-term), at minimum upgrade to the latest v3.x release, which will still fix the scroll bug you're experiencing.

The scroll issue with array inputs was a rendering bug in early v3 releases where the Studio UI wouldn't properly calculate container heights after opening array fields, preventing you from scrolling to content below. This has been resolved in later releases, so upgrading should fix your issue immediately.
