What is the motivation / use case for changing the behavior?
When using Multiselect with 3000-8000 or more items the control takes 5-6 seconds to open and every checkbox takes 3-4 seconds to register a click. Adding in Virtual Scrolling would make this control faster with large datasets. Tree Control could use similar enhancement. Datatable already supports this.

It will be better to add lazy behavior. And lazy behavior with combination with virtual scrolling will have very good performance.

Hi Team,

I am using the multiselect in my project (IE 11 and above). This works for smaller datasets.
There is a scenario were we have 2500 records to be displayed in this multiselect. But this is causing performance issues as mentioned in the above description.

Is there any fix planned for this? virtual scrolling would really help.

Thanks,
Hari

Hi Team,

Is there a limitTo attribute so that we can specify how many values should be displayed in the multi-select? This way for huge datasets we can display only say 20 values and if needed the user can search and get the values what they need.

Is this possible to do as a quick fix?

Thanks,
Hari
