List events, display event details and products. Use the Showpass purchase widget seamless purchases with no redirects, all with easy to use shortcodes. Showpass is a full event management solution, allowing organizations and individuals to organize and execute successful events. Calendar shortcode attributes Both [showpass_calendar_widget] and [showpass_embed_calendar] accept these optional attributes: display_price_patron_type_id – a positive venue-local PatronType ID. This changes displayed prices only and never filters availability, calendar contents, or ticket choices. hide_price – true or false. This hides calendar price text and the price-range filter without changing availability or ticket selection. calendar_date – a venue-local date such as 2026-09-14. calendar_timeslot – a public timeslot key used with calendar_date. calendar_special_event – one attraction special-event key, multiple comma-separated keys, or all to select every currently filterable special event. calendar_open_state – calendar (default) or special-events. Opens the Special Events tab when rich special-event content is available; otherwise keeps the calendar view. This controls the view independently of special-event filtering. When combined with a date/timeslot target, the Special Events view opens first. Any configured quantity prompt still comes first. highlight_multi_day_events_on_start_date_only – true or false. Highlights multi-day events only on their local start date. Example: [showpass_embed_calendar calendar_date="2026-09-14" calendar_timeslot="evening" calendar_special_event="opening,closing" display_price_patron_type_id="17" hide_price="false"] Special Events example: [showpass_embed_calendar is_attraction="true" event_id="YOUR_ATTRACTION_ID" calendar_special_event="all" calendar_open_state="special-events"] The new options require the corresponding calendar frontend and rebuilt SDK to be deployed before releasing this plugin update.
