Based on feedback from our Suggestions area, we have created a summary page of shortcodes used in our intranet plugins. It is available for your reference here at simpleintranet.org/shortcodes. The table of shortcodes is searchable, and shows some default and sample parameters that can be used.
Note that not all of our plugins (e.g. Events Calendar) use shortcodes, many use specific URLs. Often also you must go into the Dashboard to create unique IDs for those shortcodes that can generate multiple pages or posts with output. And just a final caution, that you can run into troubles if you try to combine too many parameters in some cases. Finally, we have also included a few examples also that we use in our live demo. Let us know if you need more if we have missed any.
