We need to load around 60000 records in Ignite UI igcombo with multi-select option. But the drop down is not loading records and not responding. Kindly let us know how to accomplish the same.
60 000 records is expected to cause troubles in rendering. You need to use the virtualization feature (api documenatation, virtualization sample), which allows the combo to render only the records that are currently in view and thus boost performance.
Please let me know if you have further questions on the matter, I will be glad to help.
