Cakephp - tree structures generatetreelist blank space spacer

I need to have blank spaces as my spacers in a tree structure.

Here is my code at the moment

    $sectors = $this->User->Sector->generatetreelist(null, null, null, '__');    
    $this->Form->input('Sector.user_id', array('options' => $sectors));

I tried nsp and also开发者_如何学JAVA the escaped version.

Any Idea ?

Thanks, Alex

Try this:

$this->User->Sector->generatetreelist(null, null, null, '&nbsp');

then, in your view:

$this->Form->input('Sector.user_id', array('options' => $sectors, 'escape' => false));

Try an ideographic space: 　, no-break space:   or one of the other whitespace characters.
