[TYPO3-mvc] form.select add empty option

[Stefan Frömken]

Thank you Claus,

for now toArray() is a good start.
For later I think a new option "addEmpty" in select-ViewHelper would be 
perfect. But your idea is a little bit better, because you can combine 
many selfdefined options with the options of the array.

If you need it quickly you can find it in the extension "fed" [1] or you can wait for 1.4 / 4.6 which I hope will include the patch :)
