C结构数组结构数组

Question

Proceeding with my project which should use a quite complex structures, I felt in a dighole. I need to declare an array of structures (Menus) each one contains an array of structures (Elements). In Visual Basic, from which I come, it will be (simplified):

type t_element
  elementID as long
  size as long
  color as long
end type

Type t_Menu
  menuID as long
  numElements as long
  elements() as t_element 
end type

Dim Menus(10) as t_menu
Redim Menus(1).elements(5)

I tried something similar in XC8 with:

typedef struct t_element
{
    char eleID;
    int size;
    int color; 
}Element;

typedef struct t_Menu
{
    char IDmenu;
    char elementNumber;
    Element elements[];
}Menus;

Hoping that this is feasable, how can I declare the array of Element inside the Menus ?

This does not work:

Menus Menu[10];   //this is OK
Element Menu[1].elements[5];  //this is not
Menu[1].(Element)elements[5]; //this is not

There is a solution? If yes, what am I doing wrong ?

See the access to the elements of the structures:

typedef struct t_element
{
    char eleID;
    int size;
    int color; 
}Element;

typedef struct t_Menu
{
    char IDmenu;
    char elementNumber;
    Element elements[100];
}Menus;

int main() 
{
    Menus menus[20];
    Element element1; 

    menus[5].elements[3].color = 1;
    menus[5].elements[3].size = 2;
    menus[5].elements[3].eleID ='a';
    menus[5].elementNumber = 1;

    element1 = menus[5].elements[3];
    int color = element1.color;  

   printf("color for menus[5].elements[3]=%d",color); 

   return 0;
