change bootstrap drop down to drop horizontal right - html

Question

I have a drop down menu that opens a row of icons underneath it (see picture 1, names and pictures were removed to maintain privacy)
I am trying to make this menu to open to the right of choose child, and not underneath it (see picture 2, of what I am trying to get. the Images will open to the right of the drop down and not under it)
My current code is:
<div class="span4">
<div class="btn-group">
<a class="btn btn-link dropdown-toggle" data-toggle="dropdown" href="#">
<h3>Choose Child</h3>
<img id="mainIcons" src="boyStudent.png" alt="boyStudent">
<span class="caret"></span></a>
<ul class="dropdown-menu">
<li>
<div class="btn-group">
<a href="parent_homepage_2.html" style="text-align:center;" class="btn btn-link operationsButtons">
<h5>A</h5>
<img id="mainIcons" src="boyStudent.png" alt="boyStudent"></a>
<a href="parent_homepage_2.html" style="text-align:center;" class="btn btn-link operationsButtons">
<h5>J</h5>
<img id="mainIcons" src="girlStudent.png" alt="girlStudent"></a>
</div>
</li>
</ul>
I tried to use the following example, that helps push the drop down to the left

Answer 2

Just add the class "pull-right" into the <ul class="dropdown-menu"> this way...
<li class="dropdown">
<a class="dropdown-toggle" href="#">Link</a>
<ul class="dropdown-menu pull-right">
<li>...</li>
</ul>
</li>

Answer 3

I just add this class to the dropdown-menu:
.rightMenu {
position:absolute;
float:right;
top: 0;
left: 160px;
}
And it aligns perfectly.

To those who may find this page in the future, the now official way of doing this is with adding the .dropdown-menu-right class to your dropdown list.
