$options = array_merge($options, $db->loadObjectList());
// build form control
$lists['custom'] = JHTML::_('select.genericlist', $options,
'filter_custom', 'class="inputbox" size="1" '.$js,
'value', 'text', $filter_custom);
If we do create custom filter lists such as this, we might want to consider extending
JHTML. For example to create a foobar group type we would create a class named
JHTMLFoobar in a file named foobar.php. We would then need to use the JHTML::
addIncludePath() method to point to the folder where the file is located.
To use the new class we would need to define methods within the class, for example
baz(). We would then be able to call baz() using JHTML::_('foobar.baz'). For
examples of existing classes we can browse the joomla.html library files.

relatively simple. The first thing we must do to implement a search filter is create the
necessary form controls:

:
value="lists['search'];?>"
class="text_area" onchange=
"document.
