Get the #state based on field_parent

@linhnm I tried with the steps mention and see the date correctly appearing on the node page.
I have tried with smart_date_recur version 4.0.3.
Can you tell me what issue you see in front end?

Here is the issue I encountered.
The instance cannot create the recurring date.

I see that the form that you have is a bit different from the one that I have, for eg. a toggle button saying "Is Registration".

What I would request you to do is try out the module on a fresh install of Drupal and try to reproduce the issue.
Once you are able to do that, can you update the description with the exact steps you followed to arrive at the problem so that someone else can also reproduce the issue?
