1) In the if view helper :

public function render($condition, $then = NULL, $else = NULL, $elseif = 
NULL) {
   if ($condition) {
     return $this->renderThenChild();
   } else {
     $renderElseIfChild = $this->renderElseIfChild();
     if ($renderElseIfChild === NULL) {
       return $this->renderElseChild();
     } else {
       return $renderElseIfChild;
     }
   }
}

and

protected function renderElseIfChild() {
   foreach ($this->childNodes as $childNode) {
     if ($childNode instanceof 
Tx_Fluid_Core_Parser_SyntaxTree_ViewHelperNode
				&& $childNode->getViewHelperClassName() === 
'Tx_SavLibraryMvc_ViewHelpers_ElseifViewHelper') {
       $childNode->setRenderingContext($this->renderingContext);
       $data = $childNode->evaluate();
       return $data;
     }
   }
   if ($this->arguments->hasArgument('elseif')) {
     return $this->arguments['elseif']['condition'] ? 
$this->arguments['elseif']['then'] : NULL;
   }
   return NULL;
}


2) The elseif viewhelper
public function render($condition) {
   if ($condition) {
     return $this->renderChildren();
   } else {
     return NULL;
   }
}
