Field Select - Default selected option not working

[shivamvinsol]

Hi, I am using Field::Select and need to show a option as selected by default.
I read the guides and it mentioned that the collection param has the same format as Rails options_for_select

options_for_select does allow selecting a option and I tried the following

collection: [['Apple', 'Ball', 'Cat'], 'Ball']
collection: [{ Apple: 1,  Ball: 2 }, 2]
collection: ['Apple', 'Ball'], selected: 'Ball'

But none of these worked.
Is there a way to do this, or do I need to add a custom field for this?

Thanks and apologies if this issue was raised earlier.
