Listing custom menu in wordpress in two stages -

I need a custom menu list in WordPress in two steps.

To list the custom menu but I would like to do something like this:

  & lt; List of first part of 'My menu' & gt; Something else, some & lt; Div & gt; Display etc ... & lt; 'My menu' & gt;   
 So my questions are:  
 
 How do I get the right number of links in my menu?  
 Is there any way from the beginning to a certain point list, and then the rest?    
 
 
 What exactly do you need to use, because this array of menu items From that point it gives only normal PHP which you want.  
 But, starting from the beginning, are you sure that you want a menu, maybe a better option is to create two menus? The menu is just an array of menu items, many of them you can create for different purposes.
