Enfold – sidebar issue

currently I am using Enfold Theme and I have an issue with sidebar menu.

basically, I am trying to show parent menu along with children menus.

I tried to use different theme and it displayed parent menu along with children menus correctly but this them does not show parent menu at the sidebar.

see example below.

basically, I want to display all A, A1, A2 at the side bar. (currenlty “A” is missing)

A

– A1

– A2

B

– B1

– B2

how can i do that?

please advise

thx
