I use Vaadin 8. My grid has component columns. One of columns is HorizontalLayout that contains TextField and MenuBar. But MenuBar disappears when i scroll the grid. When i expand the column, menubar starts to appear. But when scroll it disappears again. It just paints the parts thats seen on the screen. What do you thinks the problem is and how can i fix it?
