I added an &#8220;Event Categories&#8221; widget and its &#8220;Add filter&#8221; dropdown is just an ordinary select box rather than the fancy one that comes up when I place the widget in a main widget area. The selection is also not saved when the widget is saved. As a clue to why, I get several errors in my console, centering on this bit of the code in widget-calendar.php:<\/p>\n<p>setTimeout( function () {<br \/>\n\tjQuery( &#8220;select.calendar-widget-add-filter:not(#widget-tribe-mini-calendar-__i__-selector)&#8221; ).select2();<br \/>\n\tcalendar_toggle_all();<br \/>\n}, 600 );<\/p>\n<p>The console reports that &#8220;undefined is not a function&#8221; after the line calling select2(). Commenting out this line produces an error on calendar_toggle_all(). These are the only errors in the console, and I checked that JS was running fine up to that line. Hence I&#8217;m coming to you first rather than the Page Widgets developer (it doesn&#8217;t seem as if his code is breaking the JS), though he&#8217;ll be my next port of call.<\/p>\n<p>Have you heard of this issue before? Any thoughts? It&#8217;d be much appreciated!<\/p>\n","protected":false},"template":"","class_list":["post-133100","topic","type-topic","status-closed","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Event Calendar widget filters causing Javascript errors -<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/theeventscalendar.com\/support\/forums\/topic\/event-calendar-widget-filters-causing-javascript-errors\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Event Calendar widget filters causing Javascript errors -\" \/>\n<meta property=\"og:description\" content=\"Hi &#8211; I have a problem with the Events Calendar Pro 3.5.1 when used in conjunction with the Page Widgets plugin (this one: http:\/\/wordpress.org\/plugins\/wp-page-widget\/).
