HTML CSS Js - Arbre pliable, afficher le repli à l'ouverture

Question

J'utilise l'exemple ici https://codepen.io/ac_coding/pen/wMmKgb pour créer un menu pliable, mais je souhaite que le menu soit entièrement réduit lorsqu'il est ouvert.

J'ai essayé d'ajouter quelques modifications à Javascript comme

$('toggleClass').click()

Mais jusqu'à présent, je n'ai pas de chance.

Javascript est difficile à comprendre car je suis très nouveau dans ce domaine.

Toute aide sur la façon dont je peux m'assurer que la page s'ouvre et que toutes les options sont réduites serait grandement appréciée.

Merci beaucoup d'avance.
