How do I alter my dropdown menu?

I am wanting to create a JSP method which dynamically changes my dropdown menu, so I can dynamically populate my dropdown menu depending on the user's inputs.


-----------------------------------------------
<form name="form1" method="post" action="" >
<select name="select" >
<option>Option1</option>
<option>Option2</option>
...I want to dynamically change this dropdown menu...
</select>
</form>

<%
public void Alter_dropdownmenu(){
//How do I alter the dropdown menu above?
}
%>

You basically have 2 options.

1. When the form is submitted you will need to populated some collection object with the values for the dropdown list and populate the dropdown using JSTL (or scripts if you have to).

2. Use Javascript.

Option 1 will require you to re-write how your dropdown is rendered. Option 2 doesn't belong in this forum.

If you search this forum and the javascript forum, you'll find that this is a very common question which has been answered on numerous occasions. So other than...

//How do I alter the dropdown menu above?

...what have you tried?
