Saya baru saja selesai memposting fungsi yang mendapatkan item menu anak diberi jalur simpul. Anda dapat memeriksanya di sini: http://softkube.com/blog/getting-child-menu-items-drupal-menu-tree
Saya menyertakan tautan ke bukti di masa depan, kalau-kalau posting diperbarui dan saya juga akan menyalin / menempelkan kode lengkap di akhir.
Dalam kasus Anda, Anda dapat menjalankan sesuatu seperti ini di tema Anda untuk mendaftar semua item menu anak. Ubah echo
pernyataan dan tema sesuai keinginan Anda.
$path = current_path();
$nids = skl_get_all_menu_node_children_ids($path);
$children = node_load_multiple($nids);
foreach($children as $c) {
echo $c->title . ': ' . url('node/' $c->nid) . '<br />';
}
Dan inilah kode lengkap fungsinya. Periksa tautan untuk kemungkinan pembaruan di masa mendatang.
Semoga berhasil.

Kemudian menggunakan CSS saya bisa menata tautan untuk menghapusul
padding, membuatnya tampak semuanya pada level yang sama. Tidak ideal, tetapi efektif. EDIT: maaf, saya tidak tahu cara mendapatkan jeda baris untuk bekerja.
