add a menu to a user menu
You can use  'menu_name' =&gt; 'primary-links'; in your code and of course you have to alter the primary-links to the menu of your choice.  

$items['budget/view'] = array(  
  'title'             =&gt; t('Ver gastos'),  
  'description'       =&gt; 'Veja quanto é que anda a gastar',  
  'page callback'     =&gt; 'page_budget_view',   
  'page arguments'    =&gt; array(2,3),   
  'access callback'   =&gt; ($user-&gt;uid &gt; 0),  
  'menu_name'         =&gt; 'primary-links',  
);
