In Blue, every record has to be associated with one list. To move a record to a different list, you can use the following mutation:
mutation MoveRecordToAnotherList {
editTodo(input: { todoId: "ENTER RECORD ID", todoListId: "ENTER LIST ID" }) {
id
uid
position
title
text
html
startedAt
duedAt
timezone
color
cover
done
todoList {
id
}
}
}
