How to display menu block on menu items that do not have children ?

I want to display the submenu related to the current **menu item**

- menu item 1
-- submenu item 1
-- submenu item 2
-- submenu item 3
--- subsubmenu item 1
--- subsubmenu item 2

- menu item 2
-- submenu item 1
-- submenu item 2
-- submenu item 3

On **menu item 1**, and all direct childrent I want to display the following:

- submenu item 1
- submenu item 2
- submenu item 3
-- subsubmenu item 1
-- subsubmenu item 2

On **submenu item 1**, and all direct children I want to display the following:

--subsubmenu item 1
-- subsubmenu item 2

I have tried with Menu Block but it only works when you are on a menu item that have children. Any Idea how I could achieve this with Menu Block or any other option?
