In econfig Screen how to display required number of Products in a group

We have requirement in eConifigurator screen to display only 7 products in a group. these products are dynamic like during runtime first 7 products need to display in out of 45 products in a group. All these products are display based on eligiblity ruels. like in econfig screen display first 7 eligible products to user.

For testing purpose I copied existing template "eCfgControlRadioPriceJS.swt" and modified below code in that template

Original Code :

<swe:for-each id="500" CfgLooptype="DomainAndChildren" StartValue="1500" count="Dynamic" iteratorName="101Id"

Modified code as:

<swe:for-each id="500" CfgLoopType="DomainAndChildren" StartValue="1500" count="5" iteratorName=101Id"

in above line I changed count = "7" as original value as "Dynamic".
