expandir e fechar menu

[mauro26 0]

Oi pessoal, estou usando um script, no qual ando a ter problemas a por uma funcionalidade a dar, ele é um menu que expande e fecha, mas gostaria de fazer com que quando eu carrego um link submenu dentro do menu, ele me ficasse aberto o menu ao qual o submenu que foi carregado, agradecia que me ajudasse, o script está aqui neste site até, os links do submenu não estão activos, mas dá para terem uma ideia, o script js é o "utils.js" e o css dele é o main css, mas basicamente onde vem a funcionalidade é o utils.js

 

Abraço pessoaç. espero que me possam orientar em como resolver o problema
