It supports most features of similiar high quality commercial date pickers, but it's implemented solely as a popup window...
I choose popup, only because I find them most user friendly...
A DIV (at the time) had issues with displaying over top Flash, comboboxes, etc...
Not sure if the Flash thing has been since rectified, but I'm pretty sure layers can be displayed over top comboboxes now??? But whatever, thats not my question...
Anyways I have also found that many DIV type popups have problems with timers and closing properly or atleast promptly...
They both have their ups and downs, but I personally like popup for date pickers...
But now I ask the general community...
What would you prefer?
Cheers
