The option/value pairs are just configuration values which can be stored in each category and which can be used e.g. in the template to enable the CSS based megamenu. But you can't filter for those values as they are stored as JSON encoded string in the "config" column of the mshop_catalog table.
If you you explicitly want to filter the categories in the database by a custom value, you could add a manager decorator adding a new column to the mshop_catalog table:

okay assume i added one coloumn is_branded_category , how to write filter option , if posssible please show it in this data() function of my component (here it retrives all the category tree )
Code: Select all
public function data( \Aimeos\Base\View\Iface $view, array &$tags = [], string &$expire = null ) : \Aimeos\Base\View\Iface
{
$tree = \Aimeos\Controller\Frontend::create( $this->context(), 'catalog' )->uses( $this->domains() )
->getTree( \Aimeos\Controller\Frontend\Catalog\Iface::LIST );
$products = \Aimeos\Controller\Frontend::create( $this->context(), 'product' )->uses( $this->domains() )
->category( $tree->getChildren()->getId()->all(), 'promotion' )->search();
$this->addMetaItemCatalog( $tree, $expire, $tags );
$this->addMetaItems( $products, $expire, $tags, ['product'] );
$view->homeTree = $tree;
// $view->homeStockUrl = $this->stockUrl( $products );
return parent::data( $view, $tags, $expire );
}

The catalog controller has a compare() method where you can add custom conditions:
https://github.com/aimeos/ai-controller ... hp#L26-L35
In your example:
Code: Select all
$cntl = \Aimeos\Controller\Frontend::create( $this->context(), 'catalog' );
$categories = $cntl->compare( '==', 'is_branded_category', 1 )->slice( 0, 20 )->search();
