How add into menu container existing objects?

Normal code for menu create every in cont.
Howto add existing for example panels or (squareline components)

I test multiple lv_obj_set_parent(ui_PanelMenu1, cont);
but only first showed

Is it a container?

? i use this

  cont = lv_menu_cont_create(sub_1_page);
  lv_obj_set_parent(ui_PanelMenu0, cont);
  lv_obj_set_parent(ui_PanelMenu1, cont);
  lv_obj_set_parent(ui_PanelMenu2, cont);

  lv_group_add_obj(g1, ??? );

ui_PanelMenuX is component (combined objects from Squareline)
Repeat only one showed in menu (0 first)
And second how add to group child objects from component ?

@kisvegabor hi , is this bug or my fail steps?

it places all object on to of each other (same coordinates). Does it make the others visible?

lv_obj_set_x(ui_PanelMenu1, 100);
lv_obj_set_x(ui_PanelMenu2, 200);

Disagree panel have defined different xy, changing parent i mean dont change this.
Too one is bigger as second and i see only one

Seems created container is only for one child, and set parent dont add one.

I’m pretty sure lv_obj_set_parent works well.

Please send a more complete code snippet to reproduce the issue.
