Hi Johannes,

It's fairly simple. You can use any value as the "string" argument - in your
case I guess {hotel.name}.

You can place the ViewHelper anywhere, but I suggest the root of the
"ViewHelpers" directory (since this is not a widget). You would use this by:

1) In the template, register the namespace for your ViewHelpers, fx
{namespace hotel=Tx_Hotel_ViewHelpers}
2) Use <hotel:initialLetter string="{hotel.name}" /> in each iteration of
your <f:for> - it will only render anything if the {hotel.name} starts with
a different letter than the last time the <hotel:initialLetter> was used.
Should be exactly what you need.

There's no such thing ;) ask away!

Cheers,
Claus

use $this->viewHelperVariableContainer->add() 
 etc. Just remeber that the
ViewHelperVariableContainer requires a class name as first argument, the
following arguments are just the same as for TemplateVariableContainer.
