form_for to dynamically add multiple child objects

I have a data structure as follows: Task has_many Reminders

Now I would like to have users able to specify one or more reminder in the task form at the time when user creates the task. How could I do that? The same issue applies when I have one or more reminders being created, I would like to allow the user to modify all these reminders same time when they are modifying the task.
