Image and several lines of text in bootstrap dropdown-menu - css

Question

It's probably a silly question, but I don't understand why it doesn't work.
I need to create a bootstrap menu where each item is an image on the left and several lines of text on the right.
I wrote the following HTML for this:
<div class="btn-group">
<ul class="dropdown-menu" style="display: block;">
<li>
<a href="#" class="clearfix">
<div class="pull-left">
<span>My image</span>
</div>
<div class="pull-left">
<div>Text on the right</div>
<div>Second line of text</div>
</div>
</a>
</li>
</ul>
</div>

However, width is not calculated properly and the second floated block is moved below the first block.
I don't understand why it happens and what to do to fix this.
P.S. I know I can implement it with display: table-cell, but I just don't understand the reason why my approach doesn't work.

I think problem is how you use dropdown-menu class, try this:
<div class="btn-group">
<ul style="display: block;">
<li>
<a href="#" class="clearfix">
<div class="pull-left">
<img src="smiley.gif" alt="Smiley face" width="42" height="42">
</div>
<div class="pull-right">
<p>Text on the right</p>
<p>Second line of text</p>
</div>
</a>
</li>
</ul>
If you want use a dropdown-menu, you can look an example in this page:
