Récupérer la valeur retournée par un handle

Bonjour,

Je suis entrain de créer un menu avec des sous menu. Lorsque je clique sur un item de mon menu, je veux que cela déroule mon sous menu.
https://material-ui.com/demos/lists/ : Section Nested List

Mon problème c'est que j'appel une fonction handle et je souhaite qu'elle me retourne une valeur mais j'ai l'erreur suivante :

Citation:

But i have an error : Failed prop type: Invalid prop in of type function supplied to Collapse, expected `boolean

Mon Layout Dashboard :
