Combo Box with button in 7.3

Hi to everybody :slight_smile:

I’m trying to make a combobox grouped with a button, as seen in Valo Theme demo (http://demo.vaadin.com/valo-theme/#!comboboxes), but I don’t know where I can find info about it…

Could someone explain to me how to bind a button to a checkbox in this way? :slight_smile:

Thanks

Looking at the DOM, it seems to be a CssLayout with the style name v-component-group added. The CB and Button don’t have any specific style names.
