How to make the answer displaying without the scrollbar?(Arcade and Modern widget)

Important: This solution is only applicable to legacy widget code.

To remove the vertical scroll-bar from the embedded widget, set dynamicSize to true in your script as follows:

< !--do not modify this script -- >
< div id='NanorepEmbedContainer' >
< /div >
< script type='text/javascript' >
   var _nRepData = _nRepData || []; 
   _nRepData['kb'] = ' YOUR_KB '; 
   /* API here */; 
   _nRepData['embed'] = 
{
   account:' YOUR_ACCOUNT_NAME ', 
   container: 'NanorepEmbedContainer', 
   width:400, 
   maxHeight:0 , 
   dynamicSize: true , 
   cdcFrame:'', 
   cdcVersion:3, 
   scriptVersion: '2.22.2.31'
};

(function(){
   var windowLoadFunc = 
      function(){
         var _nRepData = window._nRepData || [];
         _nRepData['windowLoaded'] = true;
   
         if (typeof(_nRepData['windowOnload']) === 'function') 
            _nRepData['windowOnload']();};
   
   if (window.attachEvent)
      window.attachEvent('onload', windowLoadFunc);

   else if (window.addEventListener)
      window.addEventListener('load', windowLoadFunc, false);
   
   var sc = document.createElement('script');
   sc.type = 'text/javascript';
   sc.async = true;sc.defer = true;
   sc.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'my.Nanorep.com/widget/scripts/embed.js?account=ving';
   var _head = document.getElementsByTagName('head')[0];_head.appendChild(sc);
})();< /script >
