I bruefly tried the component and it works great! The only suggestion i will add is that if the user is likely to select multiple item, it is rather cumbersome because you select an item and then have to re-open and select the next item and so forth.
Do you have any plans to add a feature so the selections (while opened) would be similar to checkboxes? That way it could stay open and you can select multiple items at once.
Thank you for your feedback. I do agree that this is a setback in the component usability. Unfortunately, it comes as a limitation from the underlying vaadin-combo-box.
I have been looking into it and trying out different approaches that could make it so that the drop-down stays open whilst the user is selecting multiple items at once. The best I’ve found does require some slight modifications to the underlying vaadin-combo-box which I am unsure the team would like to introduce, but I will keep on trying and hopefully resolve this.
