I have a form that has a dropdown menu
i need the user to be able to change the value of the options in the dropdown menu by changing the value in the textbox, how would do this using jquery javascript or php?

<div id="formh">
<form id="form">
<select name="test" id="test">
<option id="op1" value="1">1234</option>
<option id="op2" value="2">2134</option>
</select>
</form>
</div>
<div id="st">
<form name="settings">
Op1 Value<input />
Op2 Value<input />
</form>
</div>

Answer 1

If i understand your question correctly it appears you want to change the value of an option from a text box.

If you give the input box an id, you could do the following:

$("#inputOpt1").change(function(){
  $("#op1").val($(this).val());
});

Example of this on jsfiddle.
