Laravel 5 eloquent recursive programming

I have then next 2 tables

/* systems */
id sys_name
1 Debtors
2 Creditors
3 Cashbook

/* menus */
id system_id parent_id menu_desc
1 1 0 Maintenance
2 1 1 Maintain Debtors
3 1 2 Debtor Addresses
4 1 1 Maintain Clerks
5 3 0 Bank Reconciliation

I have 2 Eloquent models

/* System */
public function menus(){
return this->hasMany(Menu::class,'system_id','id')->where('menus.parent_id','=',0);
public function submenus(){
return this->hasMany(Menu::class,'system_id','id')->where('menus.parent_id','=','');

/* Menu */
public function system(){
return $this->belongsTo(System::class,'system_id','id');
public function parent(){
return $this->hasOne(Menu::class,'id','parent_id');
public function children(){
return $this->hasMany(Menu::class,'parent_id','id');

I want to achieve the following in blade.php:

@foreach($systems as $system)
@foreach($menus as $menu)
@foreach($submenus as $submenu)

with the following output: (I am using bootstrap for indentation)

Maintain Debtors
Debtor Addresses
Maintain Clerks
Bank Reconciliation


$systems = System::with('menus','submenus')->get();

but it doesn’t work. There are no submenu records. I think the problem is ‘’ in function submenus() but dont know how to solve it.

Please help as I have battled more than 3 days to build a menu treeview.

Thanking you in advance
