I would like to know if there are any tutorials about the following thing that i would like to do.
I would like to add in my back end control panel of my software source a checklist that when i check a checkbox to be echoed in the front end of the store, and when i uncheck it, the option to disappear in the front end.
How can i do this?

Hi,
Maybe with JavaScript, something like this:

<form action="script.php" method="post">
 <div id="sel" style="display:none;">Select: <select name="sel">
  <option value="v1">v1</option>
  <option value="v2">v2</option>
  <option value="v3">v3</option>
 </select></div>
 Checkbox: <input type="checkbox" name="chb" id="chb" onclick="getSel(this)" /><br/>
 <input type="submit" name="submit" value="Send" />
</form>
<script type="text/javascript"><!--
// JavaScript Course: www.coursesweb.net/javascript/
function getSel(chb) {
  if(chb.checked == true) document.getElementById('sel').style.display = 'block';
  else document.getElementById('sel').style.display = 'none';
}
//-->
</script>
