<div id="my_id" style="visibility:hidden;" ><a href="/somepage">I'm special</a></div>

Display multiple items on a page
Give your items a class
<div class="SomeOtherClass DisplayMeOnClick" style="display:none;" ><a href="/somepage">I'm special</a></div>
<a href="/someotherpage" class="DisplayMeOnClick" style="display:none;" >I'm also special</a>
Your link to show the hidden items
<a href="javascript:void(0);" onclick="jQuery('.DisplayMeOnClick').show(); jQuery('.EcuHiddenAdminLink').hide();" class="EcuHiddenAdminLink" >Show Hidden Items</a>
