[TYPO3-mvc] Fluid - using an array in condition?

Right now, that's not possible without a custom ViewHelper.

The reason is that you would like to write {checkedItems.{index}}, which
is not supported right now... And from the parser side, I am not sure if
this still makes the language unambiquous. That's why I cannot guarantee
this feature will be implemented in the upcoming time.

You can, however, write an Array Access view helper, which does what you
want, with the following signature:
<my:array array="{checkedItems}" index="{index}" />
... and you can use it in the shorthand syntax as follows:
{my:array(array: checkedItems, index: index)}

This shorthand syntax can be plugged into the <f:if, and there you go:
<f:if condition="{my:array(array: checkedItems, index: index)}">

Greets,
Sebastian
