Hi Ankit,

Greetings to you!

Starting with the Spring '18 release, Admins have the ability to control the List type Custom Setting creation. By default, the "Manage List Custom Settings Type" is disabled, which is why Custom Setting type List is greyed out. To allow the creation of custom settings when using application-level data definitions you'll need to enable Manage List Custom Settings Type.

1. Go to Setup.
2. In Quick Find box, type Schema Settings.
3. Enable Manage List Custom Settings Type.

With the option enabled, you can choose List as the setting type when defining a new custom setting.

I hope it helps you.

Kindly let me know if it helps you and close your query by marking it as solved so that it can help others in the future. It will help to keep this community clean.

Thanks and Regards,
Khan Anas
