Thanks Geoff, I will have a look at it and try it out.
Another challenging next step, but nice to hear from you which way to go.
Right now I have been able to add a category to the events calendar organizer ‘post’, but haven’t been able yet to show it in a slider or blog.
I guess somewhere there has to bearded a definition that also ‘reads’ the ‘hidden’ posts form the Event Calendar.
Any suggestion how to is welcome.
