Hola a todos, llevo un tiempo intentado hacer esto pero no hay manera asi que haber si me podeis echar un cable.

Yo tengo un arbol de carpetas hecho con javascript y lo que quiero es que dependiendo del boton que pulse se expanda o se contraiga el arbol, mi codigo es este:

		window.close();
	}
	
	function arbol(opcion) {
		
	}
