catégorie sous-catégorie arbre question javascript

Question

J'ai un arbre.Il ya une catégorie et sous-catégorie comme vous pouvez le voir sur l'image.Je veux que les catégories auront la ligne inférieure, mais les sous-catégories ne seront pas. Pouvez-vous m'aider s'il vous plaît comment je peux faire ce? à partir de ce javascript?
