Script Fix to Expand All Items in SharePoint 2013 Calendar to Show More Than Three Using jQuery

I’m not really sure why Microsoft made the decision to auto-hide when you have more than three items, then make it so difficult to reset (bad Microsoft, no cookie!), but this is a quick workaround I have confirmed works even with a large number of overlay calendars and lots of events.

For testing, I recommend setting the final setTimeout to 2000 to make sure the calendars and events are all loading, then play with your final setting – I found 800 ms worked well for my environment with a bit of wiggle room and not too much lag.

JavaScript for More Than 3 Items in SharePoint Calendar

I like to put this in the Site Collection root Style Library folder or a custom AdvancedContent library folder, then reference it in a Content Editor Web Part on the calendar page where it is needed for reusability. You should also be able to just throw it in a script block, assuming you have jquery files to reference. A similar approach can be used to make a pretty and persistent Expand All button if needed.

<script src="https://sharepoint.com/it/Style Library/jquery.1.11.1.min.js"></script>
<script>
$( document ).ready(function() {
	//$("div").css("color","red");    
    
    
    var pollCount = 0;
    checkCalendar($);

function checkCalendar($) {
	//alert("Checking for Calendar load");
   //stop after 10 seconds
   if (pollCount > 20)
      return;
   //if the calendar hasn't loaded yet, then wait .5 seconds
   //if ($('.ms-acal-title a').length < 1) {
   if ($('.ms-cal-nav').length < 1) {
      pollCount++;
      setTimeout(function(){checkCalendar($);}, 500);  
      //alert("Checking " + pollCount);   
   }
   else {
      //the calendar has loaded, so do work
      	setTimeout(function(){  
      	//alert("Found title, running expand");
         var calendar = SP.UI.ApplicationPages.CalendarInstanceRepository.firstInstance();
         if (calendar && typeof calendar.expandAll === 'function') {calendar.expandAll();}
      	}, 800);
         

      //});
    }
}

    
});
</script>



Have a cup of tea! You’re Done!
