ScrollLayout: EDIT: Vaadin 14 now has the Scroller component in their core, which basically makes this here obsolete. Scroller | Components | Design System | Vaadin Docs
I haven’t checked their implementation, but I would assume they did it better than me… ;)
In Vaadin Flow, there is no Layout with a provided scroll bar. In Vaadin 8, you could use Panel.
Now you can use this add-on, which includes 2 classes: VerticalScrollLayout and HorizontalScrollLayout.
They can be used just the same as their nonscrollable VerticalLayout and HorizontalLayout counterparts.
Compatible with Vaadin 14 - bower AND npm mode.
