Hello Bob.
This plugin does not work with hover. We have created versions that dose, but you really need to think through how you will deal with touch devices that do not have a hover.
Also, when you hover over and item… how do you close it? Hover out is the easy answer, but then you can never select or click on anything in the target area.
In short, it can be done but it’s a complex interaction that needs to be well planned out.
Here is an example of a plugin we custom built for a client: https://spacedonkey.de/941/hover-o-matic-0-4-test/
If you MUST deal with hover events, then shoot us an email at info [at] twinpictures [dot] de and we can explore some options.
