Question Visual separation of script Kunena from the script Joomla

Hi, I have a question for those who use the script Kunena.

Do you give advice, and if so how visually separated kunena script from the Joomla script ?

It's exactly what I wanted to shown a forum on the entire width of the page, and displayed in a place where articles are displayed in Joomla.
On the left side I have a separate space (div) for the menu, links, etc., I would like to not be seen when the user goes to forum.

I have a problem with it because, first, that Kunena displayed by the command "<jdoc:include type="component" />" and, secondly, the left side is a separate statically in index.php why not help set the assignment in admin .

I have no idea how to make this : /

I still correspond to such a solution, the forum was to appear from another file, eg forum.php instead of index.php but unfortunately it did not have ideas how to do this.


Edit: It seems to me that one could obtain such an effect in the right place using the 'if', but unfortunately I know a little php (actually it's saying too much) and can not help myself.

Very sorry for my bad english.

You can tell modules in which pages they show up. So in Kunena if you just don't show left / right, you get the whole space for the component.
