I'm looking to allow users to filter the data that is displayed on a page based on a selection they are allowed to make [dropdown lists, check boxes, etc...]

I can't seem to find any examples of how to pull this off.

I know I could make a dataobject like the below

class Staff extends Page {
	static $db = array(
	'Department' => "Enum('Math,Science','Math')",
	'LastName' => 'Text'

	public static $has_one = array(

	static $defaults = array ( 
        'ShowInMenus' => false
   function getCMSFields() {
   $fields = parent::getCMSFields();
   $fields->addFieldToTab('Root.Content.Main', new DropdownField(
			'Select A Department:',
   return $fields;

class Staff_Controller extends Page_Controller {


And the use a page type like this to display the Math department

class MathDept extends Page {
	static $db = array(
	static $has_one = array(
   static $allowed_children = array('Staff');

class MathDept_Controller extends Page_Controller {

function DisplayMath(){ 
$DM = DataObject::get("Staff", "Department = 'Math'", "LastName", null, null); 
return $DM; 


And then I could proceed to create a bunch of different page types for each department to display the departments, by changing the filter. Even while I type this I know that must be the most amature way to pull it off... =(

I guess what I need to do is change Math in the where clause to a variable and some how allow the end user (not a CMS user) select the variable they want from from the page and click a "go" button or something of that sort. A live refresh would be in better but I have no idea how to pull this off.

Any help would be greatly appreciated!!
