                 Key: WICKET-5170
                 URL: https://issues.apache.org/jira/browse/WICKET-5170
             Project: Wicket
          Issue Type: New Feature
            Reporter: vineet semwal


Hi,
currently the only way to add new items at any index is removing all children and then adding/recreating new children ,this might be ok for listview/dataview since the ideal way of using them is to reconstruct at render ,this though ok for them but will not be good for a repeater whose size is big/growing repeater . fortunately markupcontainer provides everything to introduce a method like add(index,component) which will have functionality like List#(index,element). 
the advantages of introducing this method will be in places like an infinite scroll repeater which can prevent the growing size by removing elements at start/end depending on scroll position and later can add the items back at start or end .
