Making use jQuery's slideToggle() method could help you do this.

Example

HTML:

<div id=contact>

    Contact me!

</div>

<a href=# id=toggle>Contact</a>

CSS:

#contact

{

    display: none;

    background: grey;

    color: #FFF;

    padding: 10px;

}

JavaScript:

$(function()

{

     $(a#toggle).click(function()

     {

         $(#contact).slideToggle();

         return false;

     }); 

});
