How to get a scroll bar in combobox drop down

Is it possible to have a scrollbar for combobox? Currently, we just have an UP and DOWN arrow to navigate through all the items. We are buliding an application using Vaadin and our clients are not satisfied with the UP and DOWN arrow. I am using ValoTheme.

The paging is built very deeply into the ComboBox, changing that behaviour would require huge modifications to the component. Could you use the NativeSelect component instead? you’ll lose some features with that, though.

I remember someone creating a TableSelect at some point, but just for this feature I wouldn’t recommend you creating our own.
