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

Management:<br/>
<ul>
  <li>......</li>
  <li>Content</li>
  <li>Structure</li>
  <li>......</li>
  <li>My test (sub menu under administration)</li>
    <ul>
      <li>My view 1 (a view that I created)</li>
      <li>My view 2 (another view that I created)</li>
    </ul>    
</ul>

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.<br/>
**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.
