You should use jQuery to handle the event "onchange" and then complete the other inputs with data retrieved maybe after an Ajax request ?

Here is some kind of code you could use :

HTML Select input :

<select id="charity">
<option id="idtest">test</option>
<option id="idtest2">test2</option>
<option id="idtest3">test3</option>
<option id="idtest4">test4</option>
</select>

Javascript with jQuery :

$(function() {
$("#charity").change(function() {
var selectedOption ID = $("#charity option:selected").attr("id");
// Here is your ajax with jQuery too. Use the var "selectedOption" to know which option is selected
});
});
