Show block menu links only on certain pages I've built a menu with 20 links aprox. Then I put the block drupal creates for my menu on a region. Thing is I want some of the links to show for some pages, while others are hidden, like the option called "visibility options" on admin/structure/block/manage/block/nodenumber/

i.e.:
links 1,2 and 3 should be visible on page node/1
links 1,3 and 5 should be visible on page node/2
links 3,5 and 6 should be visible on page node/3

Any advice on how can I make it possible?

NOTE: Sorry for my english but it's not my native tongue.
Without any additional information about the links inside your menu, it seems the easiest way to structure this is to create 3 separate menus, even if some of the links inside them are repeated. 

What sort of links are those? Maybe you can use Views to create a Block that reacts to the page it's on to filter out the relevant links.
