Hello all,

My first thread here and im in need of some Javascript help. I have 3 categories: Starters, Mains and Sides, which when clicked displays any content inside my element. This is great but I would like to go that bit further and have only one element on show at any one time.

I thought it would be best to put the elements into an array but I have no idea where to go from here. Unfortunately Im not very literate with javascript which is a shame as it has alot of scope for some cool functionality.

My code so far:

<script type="text/javascript">
	function showStuff(id) {
	
	var switch_elements = new Array('starters', 'mains', 'sides');	
	
	if(document.getElementById(id).style.display == "none"){ 
		document.getElementById(id).style.display = "block"; 
	}else{ 
		document.getElementById(id).style.display = "none"; 
	}
	}
	function hideStuff(id) {
		document.getElementById(id).style.display = 'none';
	}
</script>
<p><a href="#" onclick="showStuff('starters'); return false;">Starters</a><br>
<span id="starters" style="display: none;">Starters</span></p>
          
 <p><a href="#" onclick="showStuff('mains'); return false;">Main Dishes</a><br>
<span id="mains" style="display: none;">Main Dishes</span></p>

 <p><a href="#" onclick="showStuff('sides'); return false;">Side Dishes</a><br>
<span id="sides" style="display: none;">Side Dishes</span></p>

Thanks in advance for any help with this! :)

If you will consider my advice, then the easiest way, is to show all information with just one container instead of making those 3 elements disappear. The following demo will show you how things will work.
