MultiSelect performance on large datasets

Question

Hi Syncfusion Team!When we manage a large data set on MultiSelect control (2,000+ items) it gets very slow, and if we use 'Choose All' option, UI freezes for several seconds, sometimes displaying OutOfMemory error: If you can provide a solution to this we would be very pleased!

Hi Matias,We suggest you to load the data on demand similar to virtual
scrolling feature . We have already confirmed this as feature request at our
end for all dropdown components ,You can track the below feedback link for further details about the feature. In the mean time we suggest you to refer the attached sample link which contains
workaround solution for the virtualization support.
