This addon is not working in Vaadin 23.1.2. However, it is working in 23.1.1.
Anyway, waiting for the equivalent Vaadin’s standard component that is development now.

Hey Syam, the bug was just fixed and it should work now again with Vaadin 23.1.2; but the author wrote, that it might break again with Vaadin 23.2;

Regarding the Vaadin standard component, I think it will be based on this project: https://vaadin.com/directory/component/multiselect-combo-box which you could already use. Downside is, that it does not allow for “select all” (see here: https://github.com/vaadin/platform/issues/2690)

Thanks Matthias for the info.
