Simples função JS não funciona

[DinhoPHP 1]

Olá! Eu já havia criado uma lista de favoritos como a do zap imóveis, porém não sei porque ela parou de funcionar, ao clicar na setinha, esta lista não exibe os itens em favoritos. Olhe o site do zapimóveis no modo desktop e entenderão melhor.

Desculpe amigos, mexeram no site que estou fazendo alguns ajustes, pois não sou o único trabalhando nele, e vi que não havia o carregamento do JQuery

Agradeço à todos que visualizaram.
