Widget Tree Picker – Documentation

Usage example

This widget works only with DCAs that have sorting mode set to 5 (tree)!

The following options can be set in the evalution array:

Property	Description
foreignTable	Source table.
titleField	Field used e.g. in the breadcrumb.
searchField	Field to be searched by (enables search bar).
managerHref	Link to the manager in the popup.
fieldType	Field type.
selectParents	If the field type is checkbox, parent records will be automatically selected when checking the child record.
multiple	Must be specified for checkbox.
pickerCallback	You can use a custom callback to modify records displayed in the picker. The parameters are exactly the same as in the default "label_callback".

For example implementation see below code:

$GLOBALS['TL_DCA']['tl_news']['fields']['categories'] = array
(
    'label'     => &$GLOBALS['TL_LANG']['tl_news']['categories'],
    'exclude'   => true,
    'inputType' => 'treePicker',
    'eval'      => array
    (
        'foreignTable'   => 'tl_news_category',
        'titleField'     => 'title',
        'searchField'    => 'title',
        'managerHref'    => 'do=news&table=tl_news_category',
        'fieldType'      => 'checkbox',
        'selectParents'  => true,
        'multiple'       => true,
        'pickerCallback' => function($row) {
            return $row['title'] . ' [' . $row['id'] . ']';
        }
    ),
    'sql'       => "blob NULL"
);
