Exclude blocks?

Each block has collapsiblock settings. If you set the collapsiblock setting on a specific block, this setting will override the global collapsiblock setting.

Yes it is possible to apply collapsible block on special blocks.

As open the collapsiblock.module file where you can see the
function collapsiblock_default_settings()
In that array you will see code like
'collapsiblock_block' => '[put your div class name on which block you want to apply collapsible block]',

So, Example code will be look like this :

'collapsiblock_block' => 'div.block-homepagebox',

Perhaps I don't get it... But how say in #1 they are a admin settings for that.
