Making combo boxes visible

My page allows the user to select an option from a combo box (e.g. the options are name, position, and year). How do I make another combo box visible once or after the user has selected an option from the first combo box? Help! :confused:

Code:

---

<script language='JavaScript'>
  Show () {
    document.myForm.mySelect.style.display = "";
  }
</script>

There are different ways to do it, ways that are more compliant and meet the W3C standards. You can check W3C, actually.

Anyway, you just set the display attribute. You can set it to "none" aswell. But this function name on the onChange event of the triggering box.

just a question, but wouldn't it be:

Code:

---

<script language='JavaScript'>
  Show () {
    document.myForm.mySelect.style.visibility = visible;
  }
</script>

---

? i could be wrong though...
