Apologies if this is a simple question, or I have missed something, but there doesn't appear to be a calendar or date picker under the picker toolset.
Is this correct or is it hidden away?
You're not missing it. We had one in an alpha but had to cut it. If you want, you can vote to get it in Indigo here.
In the meantime, I just tossed together a simple sample to show you how you can simulate it.
HTH!
That's great, thankyou.
