MultiSelect with very large sources

Question

I have a task to select few products from long list, about 30000 items. To select one product I use AutoComplete. When the list is shorter, Multiselect component works perfect. Could you please to make the sample how to use Multiselect with large data sources? If it is not possible, please, plan to develop Multiselect AutoComplete to pair MultiSelect Dropdown.

Hi Stanislav, 
 
Greetings from Syncfusion support. 
 
We have validated the reported requirement and found that we can achieve your requirement by using ‘EnableVirtualization’ property set to true . Which will loads the data on demand (When scrolling) . So, for large number of data it populates the popup with limited number of data initially and loads the data while scrolling if the user needs. Kindly refer the below demo and documentation for your reference.
