I am trying to explore the below mentioned demo of multiselect with virtualization on my local machine, as per the demo i have created all the required html, script and web service.

It is showing me the result from the web service but when i try to select an item it is throwing the error. I have attached the error screenshot.

Can you please help me understand the issue.

Hi Himanshu,

The error message you shared is thrown by our online demo or by the Web app you are working on? 

If it is the online demo, can share the steps to replicate the issue?

Otherwise, I would need to see the implementation you have. Markup, Backend, related scripts. That will give me a better understanding of how the component is configured and I will be able to detect any conflicts.

I look forward to your reply.
