if possible Optiongroup.additem layout component or images form allitem
What do you mean?
optiongroup add item image and lable
You can use FlexibleOptionGroup - Vaadin Add-on Directory for that. With the default OptionGroup it’s not possible.
its possible to use vaadin7 and vaadin8
Vaadin 7
Any other option in vaadin8
Easiest would probably be migrating that add-on for Vaadin 8
RadioButtonGroup vaadin8 how to image add
FlexibleOptionGroup vaadin8 not work
Migrate FlexibleOptionGroup for Vaadin 8
thank you
