Angular2 How to write an effective method to highlight the active menu in navbar

In my application, the navbar has upto 2 levels of submenu. My requirement is to change few features of a menu when either it is selected or any of its submenu (of any level) is selected. I have been given this code that does it in an ineffective way till date (ie) writing one function for every in navbar which will make all of its specific CSS/image changes. But I would like to find an effective way (mostly one method) which will perform all the CSS changes when required data is provided as input.

<div class="col-lg-11 col-md-11 col-sm-11 col-xs-11" id="content">

</div>
In this code excerpt, when I select a submenu say 'Location', then its main menu 'Company Structure' should be changed with the following CSS values.
1) A different image should be loaded for this menu
2) background color to be changed
3) Color of caret symbol to be changed
4) A different colored border-left to be included
5) Background color of 'Location' submenu should be changed.
Similar CSS change should happen when clicking on 2 level submenu too like 'General configuration' in the example.
Any suggestions to come up with an effective way to meet this requirement is welcome. Thank you!

angularjs: uib dropdown submenu not working

Can anybody suggest what I am missing in below html to add submenu to bootstrap dropdown?
<div class="btn-group" uib-dropdown>
<button id="split-button" type="button" class="btn btn-danger">Action</button>
<button type="button" class="btn btn-danger" uib-dropdown-toggle>
<span class="caret"></span>
<span class="sr-only">Split button!</span>
</button>
<ul class="uib-dropdown-menu" role="menu" aria-labelledby="split-button">
<li><a ui-sref="a">a</a></li>
<li><a ui-sref="b">b</a></li>
<li><a ui-sref="c">c</a></li>
<li><a ui-sref="d">d</a></li>
<li class="dropdown-submenu">
e
<ul class="dropdown-menu">
<li><a ui-sref="e1">e1 (sub of e)</a></li>
</ul>
</li>
</ul>
</div>
EDIT 1
Added plunker

Because uibDropDown directive restricted to attribute.
You should write
<ul uib-dropdown-menu="" role="menu" aria-labelledby="split-button">

Bootstrap dropdown issues. (Dropdowns ans remains dropdowned)

I want to use bootstrap dropdown menu:
<li class="nav__item dropdown profile open">
<a id="openLessons" href="#" class=" nav__link dropdown-toggle" data-toggle="dropdown">
Открытые уроки
</a>
<ul class="dropdown-menu newmenu">
<li class="">Алгебра</li>
<li class="">Литература</li>
<li class="">Русский язык</li>
<li class="">История</li>
</ul>
</li>
For some reason it's dropdowned when the page loads and rmains dropdowned.
What have I forgotten?
Fiddle of course.

Remove .open
<li class="nav__item dropdown profile open">

<li class="nav__item dropdown profile open">
remove the class open.

Bootstrap - Custom Content In Dropdowns?

As the title states, I'm looking to have one single dropdown then have other HTML content in another dropdown submenu, making the dropdown act as a pop out for HTML content. The issue I'm having so far is that once I try just putting a div and code into the UL tag for the secondary drop down, it no longer stays visible on hover. Here is my current markup,
<li class="dropdown">
<a class="dropdown-toggle" id="drop4" role="button" data-toggle="dropdown" href="#">GAMES <i class="icon-caret-down"></i></a>
<ul id="menu1" class="dropdown-menu" role="menu" aria-labelledby="drop4">
<li role="presentation" class="dropdown-submenu"><a role="menuitem" tabindex="-1" href="#">Battlefield 3</a>
<ul class="dropdown-menu">
<div>
<h1 style="color: #333;">Things</h1>
</div>
</ul>
</li>
The markup is to be honest horrendous as of now, but is there an easier way to have custom content in a Bootstrap sub drop down? This way is causing miles upon miles of issues.

You can think of this way:
<ul class="unstyled">
<li class="dropdown">
<a class="dropdown-toggle btn" id="drop4" role="button" data-toggle="dropdown" href="#">GAMES <b class="caret"></b></a>
<ul id="menu1" class="dropdown-menu" role="menu" aria-labelledby="drop4">
<li role="presentation" class="dropdown-submenu"><a role="menuitem" tabindex="-1" href="#">Battlefield 3</a>
<ul class="dropdown-menu">
<li>
<div class="custom">
<h1 style="color: #333;">Things</h1>
</div>
</li>
</ul>
</li>
</ul>
</li>
</ul>
This makes the menu more semantically correct and valid... I feel something you might require in the CSS is:
.custom {padding: 0 10px;}
.custom h1 {font-size: 1.5em; margin: 0; padding: 0;}

If you don't need the other children and you're just looking for a rich dropdown, perhaps you want to be using the Popover component instead of the Dropdown component.

Update for Bootstrap 4 - it's now easy to add custom HTML to dropdowns:
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle btn-sm" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item active" href="#">Option one</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<a class="dropdown-item" href="#">
<div class="row">
<div class="col">Html</div>
<div class="col">Content</div>
<div class="col">Here</div>
</div>
</a>
</div>
</div>
