anchor function for in page links

[eluser]vertmonkee[/eluser]
At the top of my page I will have links to jump to different id's within the same page like this

Code:

<a href="#id-1">First section</a>
<a href="#id-2">Second section</a>
<a href="#id-3">Third section</a>

If I use the anchor function from codeigniter like this

Code:

<?php echo anchor('#id-1', 'First section'); ?>

It creates a link to the full url where as I just want it to move the page down to that id.

If I just put the regular <a> tag in it works fine.

Is there a way to do this with codeigniter or should I just stick with the HTML tags?

Thanks
