You can use a JavaScript function to modify the options available in a pull-down box on the page.
The following example adds a new blank selection at the top of the ''starthour'' field at Level 2:
<pre>
try{
document.forms[0].starthour.add(new Option("", "", true, true), document.forms[0].starthour.options[0])
}
catch(e){ //in IE, try the below version instead of add()
document.forms[0].starthour.add(new Option("", "", true, true), 0)
}
</pre>
