<h2>Right-aligned Dropdown</h2>
<p>Use the w3-right class to float the dropdown to the right, and use CSS to position the dropdown content (right:0 will make the dropdown menu go from right to left).</p>
<div class="w3-dropdown-hover w3-right">
<button class="w3-button w3-black">Dropdown</button>
<div class="w3-dropdown-content w3-bar-block w3-border" style="right:0">
<a href="#" class="w3-bar-item w3-button">Link 1</a>
<a href="#" class="w3-bar-item w3-button">Link 2</a>
<a href="#" class="w3-bar-item w3-button">Link 3</a>
</div>

<div class="w3-clear"></div>
<p>Note: Remember to clear floats if you use w3-right or w3-left. Remove the div class="w3-clear" to understand why.</p>
