News list and detail in center of the page problem

[leMich]

Hi,

i created a custom homepage where i list many News summaries.
My question is, when i click on "More" or the title of one news,
how can i display the content at the same place and erase
the news sumamries list ?

Actually if i make :
{content}
{cms_module module='news' number='5' category='' lang='fr_FR' dateformat='%b %d  %Y'},
the detail of the news appears first, but under the summaries are present, but i don't want them to stay !

I tried another thing, that do not work (nothing happens) :
{cms_module module='news' number='5' category='' lang='fr_FR' dateformat='%b %d  %Y' detailtemplate='mytemplate.tpl'}

Can someone help me please !
