The filtering function in Calendar Plus can be used to display only events with certain parameters. Filtering applies across all views in the calendar, so you could see only the events for one participant categorized by priority in the timeline view, for example. You can find it to the right of the timeline and unit tabs.
Clicking the filter button will open the filtering window where you will be able to select any value you have set in a choice or multiple choice field In your Calendar Plus Entries table, as well as values in the Participants / Attendees text field.
Multiple choices can be made in this window and the Calendar will display only events which match at least one of the selected values.
The search box is useful for finding records with a particular description and for filtering by description. It is on the top right hand side of the screen.
Enter an Event description name (or part of one) here and the calendar will jump to the first event whose description contains your search string. The calendar will also filter out all events that do not match your search. This function is particularly useful if you like to use week, day, or units view – since you can jump straight to an event if you know its description, instead of clicking through a bunch of dates.
