Hi Jason,

Have you tried this?

If you are OK with having to save the page to update what properties are shown/hidden, you can do this completely without dojo. If you make the property that decides what properties to show required and don't intend to change it's value frequently - that could work. 

Add an editor descriptor like this:

[EditorDescriptorRegistration(TargetType = typeof(string), UIHint = "hideiffoo")]
public class HidePropertyEditorDescriptor : EditorDescriptor
{
    public override void ModifyMetadata(ExtendedMetadata metadata, IEnumerable<Attribute> attributes)
    {
        base.ModifyMetadata(metadata, attributes);

        var contentMetadata = (ContentDataMetadata)metadata;
        var ownerContent = contentMetadata.OwnerContent;

        var myPage = ownerContent as MyPageType;

        if (myPage?.Foo)
        {
            metadata.ShowForEdit = false;
        }
    }
}

Then just add [UIHint("hideiffoo")] to the property you want to hide if the property Foo is true.

Kinda quick and dirty, but I think it will work.

The alloy plugin worked beautifully. It does it all for me. Exactly what i was looking for! Thanks guys.
