Hello., can you tell me any method how to add the menu example that
are " Search " Member Lists ETC., because i try with one plugin but
don't work ., ? can you suggest me any method how to add a menu ?

Do you mean add an item onto that menu? If so, open the 'header' template and look for

<li><a href="{$mybb->settings['bburl']}/misc.php?action=help"><img src="{$theme['imgdir']}/toplinks/help.gif" alt="" title="" />{$lang->toplinks_help}</a></li>

Copy and paste that and simply change the parts you need.
