The ListWidget class goes a long way towards making it easy to work with input widgets for lists of options. One of the most common uses of it is for building filtering interfaces based on a picktable in your syntax database. Usually, to do so you have to jump through a small number of hoops.

pxdb_import( 'content.output.pxdb_picktable' );
$picks = new pxdb_picktable( 'topics' );
$topics = $picks->get_listwidget_array();

// add default 'All' option at top
$topics = array_unshift( $topics, array( 'value' => '', 'label'=>'All' ) );
$topicsList= new ListWidget( $topics, 'topic' ); 

Now in cvs, is a single function that replicates the above lines. Its signature is list_from_picktable( $form_element_name, $pick_table_name, $additional_elements). The $additional_elements parameter is primarily there for adding a default or 'All' element at the beginning of your list.

$topicsList = list_from_picktable( 'topic', 'topics', array( 'value' => '', 'label'=>'All' ) );
