This could be a five star plugin, but the project has been abandoned by the developer. He is also unwilling to let anyone in to help maintain it. As of this writing, the documentation site is down and has been for months due to an IP address change at Siteground, the fix is a ten minute effort. There are some problems, so just realize that if you run with this and hit an issue, you’re on your own. I’m using it because I incorporated it into other work before it was abandoned and it’s non-trivial to switch to another framework. If you’re new to this, look elsewhere.

There is a little learning curve but it’s not bad. Lot’s of great options available.

It is one of the best option framework I’ve ever used. Simply too good. Thankyou very much of all the contributors of this great plugin.
