Here's a long-winded way that may help point you in the right direction by putting the menus in functions:

Code:
#!/bin/bash


function main_menu()
{
    while :
    do
        echo
        echo "MAIN MENU"
        echo
        echo "1. Main Menu Option 1"
        echo "2. Main Menu Option 2"
        echo "3. Main Menu Option 3 To Sub-Menu"
        echo "4. Main Menu Option 4 To Quit"
        echo
        read -p "Choice: " m_choice
        echo
        
        case "$m_choice" in 
            1)  echo "Main Menu Option 1"
                echo
                ;;
            2)  echo "Main Menu Option 2"
                echo
                ;;
            3)  sub_menu
                ;;
            4)  exit 0
                ;;
            *)  echo "Bad Option"
                echo
                ;;
        esac
    done
}

function sub_menu()
{
    while :
    do
        echo
        echo "SUB MENU"
        echo
        echo "1. Sub-Menu Option 1"
        echo "2. Sub-Menu Option 2"
        echo "3. Sub-Menu Option 3 Back To Main Menu"
        read -p "Choice: " s_choice
        echo

        case "$s_choice" in
            1)  echo "Sub-Menu Option 1"
                echo
                ;;
            2)  echo "Sub-Menu Option 2"
                echo
                ;;
            3)  main_menu
                ;;
            *)  echo "Bad Option"
                echo
                ;;
        esac
    done
}

main_menu

exit 0

Hope this helps.

set_item_value

menu_item_value(3CURSES)				     Curses Library Functions					  menu_item_value(3CURSES)

NAME

       menu_item_value, set_item_value, item_value - set and get menus item values

SYNOPSIS

       cc [ flag... ] file... -lmenu  -lcurses	[ library... ]
       #include <menu.h>

       int set_item_value(ITEM *item, int bool);

       int item_value(ITEM *item);

DESCRIPTION

       Unlike  single-valued  menus,  multi-valued  menus  enable  the end-user to select one or more items from a menu. set_item_value() sets the
       selected value of the item -- TRUE (selected) or FALSE (not selected). set_item_value() may be used only with multi-valued menus. To make a
       menu multi-valued, use set_menu_opts or menu_opts_off() to turn off the option O_ONEVALUE. (See menu_opts(3CURSES)).

       item_value() returns the select value of item, either TRUE (selected) or FALSE (unselected).

RETURN VALUES

       set_item_value() returns one of the following:

       E_OK		   The routine returned successfully.

       E_SYSTEM_ERROR	   System error.

       E_REQUEST_DENIED    The menu driver could not process the request.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
