hi,
look on component contact how works filter category when have contact list view.
the file have check following:
- administrator/components/com_weblinks/views/weblinks/view.html.php
, specially code

the following line allow maintain category selected.

$filter_catid = $mainframe->getuserstatefromrequest( $option.'filter_catid', 'filter_catid', 0, 'int' );


this create html list box
$lists['catid'] = jhtml::_('list.category',  'filter_catid', $option, intval( $filter_catid ), $javascript );

to create custom list (sample):

code: select all

  $db =& jfactory::getdbo();

  $menus[] = jhtml::_('select.option',  '-1', '- '. jtext::_( 'select menu' ) .' -' );
  $query = 'select id value, name text'
            . ' #__menu'
            . ' order name'
            ;
            $db->setquery( $query );
            $menus = array_merge( $menus, $db->loadobjectlist() );

            $menus = jhtml::_('select.genericlist',   $menus, 'filter_secid', 'class="inputbox" size="1" '. $javascript, 'value', 'text', $active );


i hope you!
