The multi-select and select now has the capability to handle server side filtering, i.e. an Appsmith dev can now choose to call an api on search or options using the onFilterUpdate action
We have now separated the multi-select from the select widget, This has simplified the implementation and helped us resolve any issues we where facing because of the complexity bought by both under the same hood and has also increased the discoverability of the widget for our end users. We have also simultaneously taken up multiple enhancements related to the select and multi-select widget.
