I have created one view with the help of views bulk operations and now I want one of the field to able to sort records according to the field value.
I am attaching image
How can I make the "credits" field as sorting field.
This has nothing to do with VBO. It is simply a setting in the "Table" format. To achieve this:
Click "Settings" besides "Table" format.
And select which field you need to make sortable.
