[su_expand] does not work properly

Try to reduce height for collapsed state.

Thanks, reduced to 0 and it works!

That is no minor point. I like your plugin, but I was about to abandon it because I could not get this feature to work right (apparently). I think you should include a comment about it in your primary documentation and features list. I spent hours searching for a solution. My last resort was to come hear and leave a post.
