The [cdaily_event] short code lists a single event's details. You can use it two different ways.
To always display a specific event, add the by_id argument to the short code. E.G.
[cdaily_event by_id="3333"]
Alternatively, you can put the short code on a page, and pass the ID of the event. For Example, if you have a page
/single-event/
then to list a specific event, add the [cdaily_event] shortcode and then call the page with the cal_item_id as an argument. For Example:
/single-event/?cal_item_id=3333
To find the cal_item_id, in the cloud-calendar click on the event to edit it. The cal_item_id will be displayed in your browser's address bar. See below.
You should also set the value for View Event Details URL in System Configuration.
