Bug 1333065

Description of problem
======================

It's not possible to click on any item from seconday vertical navigation menu
of *Admin* section[1] when the primary *Admin* menu item itself is selected,
because the secondary menu hides itself when one tries to reach it.

[1] secondary vertical *Admin* menu contains links to Tasks, Events, Users,
LDAP and Email settings.

Version-Release number of selected component
============================================

rhscon-ui-0.0.28-1.el7scon.noarch

Other usm packages from usm master server:

rhscon-core-0.0.14-1.el7scon.x86_64
rhscon-ceph-0.0.11-1.el7scon.x86_64

How reproducible
================

100 %

Steps to Reproduce
==================

1. Following the documentation, install USM (note that any other operation,
   including accepting nodes is not necessary to reproduce this issue).
2. Login as an admin user to the web interface.
3. Click on *Admin* item in the left primary vertical navigation menu.
4. Try to click on *Tasks* item in the Admin secondary vertical nav. menu.

Note: this is a general issue, one can try this with Storage secondary menu
with the same results (click on Storage and then trying to reach Pools or RBDs
items).

Actual results
==============

The secondary *Admin* menu is shown with all it's items, but when I move curson
into the area of the secondary menu, it dissappears which prevents me to click
on any item in the secondary menu.

That said, there is a workaround: when I click on *Storage* item to select
*Storage* menu instead, I'm able to reach items in *Admin* secondary menu by:

 * moving the curson above the *Admin* item in the primary menu without
   clicking on it (which makes the secondary *Admin* menu displayed)
 * clicking on any secondary *Admin* item (eg. *Tasks*) is possible,
   because this time the secondary menu doesn't disappear

Expected results
================

When the *Admin* item in the primary vertical menu is selected, I'm able to
click on any item from the secondary menu, such as: *Tasks*, *Events*, *Users*
and so on.
