Wow, I’m confused already. But I think that you mean you want the front page to show only the slider, with nothing below it — no front page content, no posts, no post excerpts, right?
You will need to hide that page content using some custom CSS. It’s impossible to tell you the exact code without seeing your site, however, so I’ll give you a couple of hints:
1) Use Firebug.
2) Read this: http://blog.kjodle.net/2012/02/24/styling-wordpress-posts-pages-archives-and-home-pages-by-class/
then use code like this in your custom CSS or child theme stylesheet:
.home #post-371 {display:none;}
Your actual code will include a number other than ‘371’. You’ll need those two clues above to figure out what it is. If you have trouble figuring it out, post a link.
Cheers,
