drop down + create input field

hi,

I'm working on a form and I'd like to create a new text field only when a user clicks on a specific item in the drop down menu.

i've looked around but haven't found anything yet..
perhaps somebody can help me?

thanks

This is what i got:

<input name="chk" type="checkbox" onClick="create();" value="">
<input name="name" type="text" id="name" />

 

ok i found a useful code

<script language="JavaScript">
<!--
function Show_Stuff(Click_Menu)
// Function that will swap the display/no display for
// all content within span tags
{
if (Click_Menu.style.display == "none")
{
Click_Menu.style.display = "";
}
else
{
Click_Menu.style.display = "none";
}
}
-->
</script>


 
 

<input name="chk" type="checkbox" onmousedown="Show_Stuff(display1);" value="">
<span ID="display1" style="display: none">
<input name="name" type="text" id="name" />

Code (markup):

thanks
