What hook_form_alter code do I need to change an exposed filter from a text field to a select box search? I have a view that has an age to and and from fields, and others also that I want TO and FROM. 

These are integer fields, so drop down select doesn't work, better exposed filters is also not an option.

What CSS, or Java script can I put in the Hook_form_alter to make this work?

Website that has the form is www.vuxi.com
If you would like to go for specific implementation using hook alter this would be great option.

function mymodule_form_alter(&amp;$form, &amp;$form_state, $form_id) {
  if ($form_id == 'views_exposed_form') {
    $view = $form_state['view'];
    if ($view-&gt;name == 'my_view_machine_name' &amp;&amp; $view-&gt;current_display == 'display_name') {
      // alter your exposed form here
      $addition[$field_name] = array(
        '#attributes' =&gt; array(
          'class' =&gt; array(
            // you can define you class overhere
          ),
        ),
      ),
    }
  }
}
