How to make double nested Menus in the sidebar?

[firstake-online]

I tried making a double nested side menu using the following code-

Menu::make(__('Out Menu'))
            ->list([
                Menu::make(__('Test'))
                ->list([
                    Menu::make(__('Test 1'))
                        ->icon('drawer'),
                    ]),
                    Menu::make(__('Test 2'))
                    ->icon('user'),
                    Menu::make(__('Test 3'))
                    ->icon('user'),
                    Menu::make(__('Haha 3'))
                    ->icon('user'),
                    Menu::make(__('Uhu2'))
                    ->icon('user'),
            ])
            ->icon('user'),

But it behaviour is not as expected. When I open the "Out Menu" and then try to open the Inner menu "Test" then the outer menu closes along with inner menu opening.
Any ideas to fix this issue?

So I figured out that the issue was happening due to "data-bs-target" being set to "#headerMenuCollapse" as default to all nested dropdown menus. So when I try to open the inner menu, since its parent is same as outer menu it was toggling the state of the outer menu too.

Fixed the issue by adding a parent attribute in the Menu class and setting it explicitly while creating the sub-menu.

         Menu::make(__('Out Menu'))
            ->slug('out-menu')
            ->list([
                Menu::make(__('Test'))
                ->slug('in-menu')
                ->parent('out-menu')
                ->list([
                    Menu::make(__('Test 1'))
                        ->slug('in-menu1')
                        ->icon('drawer'),
                    ]),
                Menu::make(__('Test Haha'))
                ->slug('in-menu2')
                ->parent('out-menu')
                ->list([
                    Menu::make(__('Test 67'))
                        ->slug('in-menu1')
                        ->icon('drawer'),
                    ]),
                Menu::make(__('Test 2'))
                ->icon('user'),
                Menu::make(__('Test 3'))
                ->icon('user'),
                Menu::make(__('Haha 3'))
                ->icon('user'),
                Menu::make(__('Uhu2'))
                ->icon('user'),
            ])
            ->icon('user')
