This is an experimental Vaadin add-on that encapsulates a vaadin-combo-box HTML element in a Vaadin component.
Currently, this add-on is intended to serve as an example of the Elements add-on. It probably makes no sense to use this add-on instead of the ComboBox component from the core, but I hope it inspires you to wrap other Web Components with a plain Java API!
There's a guide that explains how this add-on was implemented. You can find it at https://vaadin.com/blog/-/blogs/using-vaadin-elements-with-vaadin-framework
