Can the themes be used with 3rd Party Controls, or custom controls?
Yes. You can easily copy and paste bits from any existing template, and take it to the the new/blank template of a 3rd party control and modify it to fit that control. As you can imagine, there are way too many 3rd Party Controls for us to automatically support, so we don’t provide technical support for this. However, we do have theme customization services where you can pay to have such templates designed for you.
