Hide/Show group of components

Hi guys,

Which is the best way to group a number of components to hide and show after a button click event?

Do have I use “setVisible” for each components or there is something like “DIV” (in html) that can I use in vaadin to group them in a single component to call setVisible just one time?

I tried to use a new layout that contains the group of components , but my problem is the alignment: the captions of the two different formLayouts (that I used) are not aligned because the longest caption of the first layout is smaller than the longest caption of the first… (The two formLayouts are inside a VerticalLayout)

Can you help me?

Thanks in advance
