HorizontalLayout and components description

Hi, I have a small problem with horizontallayout. Components, which have description arent in one line with rest. How could I move all components to lower limit? Just look on datefield Test2 and button Search.

You can set the component alignment:

HorizontalLayout horizontalLayout = new HorizontalLayout();
horizontalLayout.addComponent(new TextField("Caption"));

TextField textFieldWithoutCaption = new TextField();
horizontalLayout.setComponentAlignment(textFieldWithoutCaption, Alignment.BOTTOM_LEFT);
