Adding sub menu to Management menu

Question

I'm trying to add a sub-menu under administration, for example:

Management:

• ......
• Content
• Structure
• ......
• My test (sub menu under administration)
• My view 1 (a view that I created)
• My view 2 (another view that I created)

Under structure-> menu, I see that I can create a new menu and add link to existing menues, but I cannot understand how can I add a sub menu to Management.
Note: I'm using Drupal 7.

Edit: I added a link (My test) under management (Like in @Clive's answer) with path admin/test under My Test I created another link with path admin/test/form-view-test-3 and also gave that path to the view.

When I click on My menu I what to see a list of subcategories, in my case Some view. Instead Test 3 (The View) appears as overlay tab and I see the list of admin menus.

Answer 1

1. Go to admin/structure/menu/manage/management; you'll see all the links currently in the menu.
2. Click "Add link"
3. Fill in the title, path and any other relevant data.
4. Click "Save"
5. Re-order the menu items if necessary
6. Repeat the process for as many links as you need to place under the new top-level item you just created.
7. If you're using the Admin Menu module, you might need to flush caches before changes take effect (but you might not).
