Timo Rantalaiho commented on WICKET-1969:
-----------------------------------------

By overriding newItem you can do this quite easily already.
There's already OddEvenItem (or OddEvenRowItem or something
like that).

> Having an IRepeatableBehavior for repeatable views  (allowing hooking into populateItem) would be quite useful. There are quite common tasks one could stuff into those behaviors, e.g.
> * apply CSS class names to list item element dependent on index (e.g. first, last, odd, even)
> * output separators for all but the last item
> * show/hide elements depending on index, e.g. to clear CSS float after 5 items or display table header row every 20th line
> Things like that are implemented frequently. Sublassing every repeatable once for this purpose would be an option, however I think this would be better as behavior, even more since there are several types of repeatable components.
