javascript - How to remove Conflict in a jQuery plugin in a wordpress website? -

thanks in advance , support. have tried every thing i'm bit stumped this:

i working on wordpress website. have few filters of jquery in , working fine (i initiate these plugins using):

jquery(document).ready(function($){   /*code here*/ }); 

i using jquery plugin "filter.js" having conflicting issues. when not initiate plugin (only on linking plugin file page) shows jquery conflict , can see in console:

uncaught typeerror: cannot read property 'fn' of undefined  

you can find plugin source here.

try wrapping code this:

(function($){      $(document).ready(function(){          //document ready code here     });  })(jquery); 

wrap filter.js plugin same wrapper, ie:

(function($){      //filter.js code here  })(jquery); 

if that's not working - make sure jquery included on page.
