Anyone know of a way or a script that will allow a dropdown menu to open a link without having to hit a submit button? like an onchange command or something?

Be VERY careful, some people use the keyboard for navigation, this could trigger the change everytime they try to LOOK at another option.

If you are going to use a <select> as a navigation tool then this is _essential_ reading: http://www.cs.tut.fi/~jkorpela/forms/navmenu.html

<select onChange="this.form.submit()">

Not recommended because the other form fields cold be empty.

If you use it, it is s agood idea to have a default pre-selected option.

<select onchange="window.open(this.options[this.selectedIndex].value);">
 <option value="http://www.yahoo.com">yahoo</option>
 <option value="http://www.google.com">google</option>
</select>
</form>

but be warned of what dorward has emphasized on his comment.

Another similar method to the ones posted:

<FORM NAME="GoList">
<SELECT NAME="list" onChange="window.location=this.options[this.selectedIndex].value">
<option>Make a selection</option>
<option value="default.htm">Back to Home Page</option>
<option value="resume.htm">View my Resume</option>
</SELECT>
</FORM>
