[Typo3] fce do not render if empty

[Henry Wilhelm]

Hello, list
so i try a second time, because nobody answered the same question i 
wrote a few weeks ago. Is it possible, that nobody else has the same 
problem, and nobody knows a solution?
following problem:

I have made some FCEs for example with header-field and bodytext-field.
How can I suppress rendering of fields if they are empty (no text was 
inserted in backend)? Or even suppress rendering of anything, if every 
field is left empty?

thanks,
henry
