[Boost-users] How to sort multi_index_container + composite_key + Sort by Vale. Is it possible?

Is it possible to sort the container by value? In below example by "member<Element_Entry,size_t,&Element_Entry::Id>" Or also other keys like: Sort by "member<Element_Entry,size_t,&Element_Entry::Index>" typedef multi_index_container< Element_Entry, indexed_by< ordered_non_unique< composite_key< Element_Entry, member<Element_Entry,size_t,&Element_Entry::MatId>, member<Element_Entry,double,&Element_Entry::Thickness>, member<Element_Entry,double,&Element_Entry::Angle>, member<Element_Entry,size_t,&Element_Entry::Index> > >, ordered_unique< member<Element_Entry,size_t,&Element_Entry::Id> > >

ElementRecord;
