How to divide vaadin form in sections

Hi,

I need to divide a form in sections so that user clearly understand logical grouping

e.g.

–Employee ------------------------------------------------------------------------------------------------

Name:
Salary:

–Activity in CRM ----------------------------------------------------------------------------------------

Count :

etc.

Activity in HR ----------------------------------------------------------------------------------------

Count :

I have seen many of post about Nested form, but I’m not sure to just section heading I need to divide my single form into multiple form.

Please share your solution if implemented otheriwse any exeprience or thought on it would be great.

Thank you In Advance
