I have used "SelectList" cusotm field type in transition screen.

It contains "None" as first option in select list field.

I have marked "Required" in field configuration. Though, it allows to select "None" while submit the transition. i want it to be mandatory validation to select other then "None" in transition screen.

OP didn't seem to be asking how to remove NONE.

He's asking "How can I make choosing a value other than NONE mandatory?"

Alternatively, you can remove the 'None' from the Select list options by referring to the following links:

You have to define a default value for the customfield in the field configuration.
