My b2evolution Version: Not Entered

I want to handle the title area and content area for each sidebar block seperately...

so i did use ;

	<?php
		// ------------------------- "Sidebar" CONTAINER EMBEDDED HERE --------------------------
		// Display container contents:
		skin_container( NT_('Sidebar'), array(
				// The following (optional) params will be used as defaults for widgets included in this container:
				// This will enclose each widget in a block:
				'block_start' => '<div id="$wi_class$" class="sidebar-box">',
				'block_end' => '</div></div>',
				// This will enclose the title of each widget:
				'block_title_start' => '<h3 class="sb-title">',
				'block_title_end' => '</h3><div class="sb-content">',
				// If a widget displays a list, this will enclose that list:
				'list_start' => '<ul>',
				'list_end' => '</ul>',
				// This will enclose each item in a list:
				'item_start' => '<li>',
				'item_end' => '</li>',
				// This will enclose sub-lists in a list:
				'group_start' => '<ul>',
				'group_end' => '</ul>',
				// This will enclose (foot)notes:
				'notes_start' => '<div class="notes">',
				'notes_end' => '</div>',
			) );
		// ----------------------------- END OF "Sidebar" CONTAINER -----------------------------
	?>

however as you know, some widgets as "blog tagline" does not have a title-h3- so that it doesnt get the "<div class="content>" right after the title which breaks the order...

any ideas how can i achieve this ?
