How to navigate a complex object via keypad?

How-to

Description

I created menu-like object with lv_obj_create():

It has some items, each item has a label and switch.

But I could not figure out how to navigate this by using keypad.
For example, I want to use LV_KEY_LEFT or LV_KEY_RIGHT to select one of these items, and press LV_KEY_ENTER to enter the edit mode of the switch.

But for now, any key of LV_KEY_LEFT, LV_KEY_RIGHT and LV_KEY_ENTER only control state of the first switch, like:

Code to reproduce

static void lv_setting_test(void)
{
  lv_obj_t *menu = lv_obj_create(lv_scr_act());
  lv_obj_set_size(menu, 300, 150);
  lv_obj_set_align(menu, LV_ALIGN_CENTER);
  lv_obj_set_scroll_snap_y(menu, LV_SCROLL_SNAP_CENTER);
  lv_obj_set_flex_flow(menu, LV_FLEX_FLOW_COLUMN);
  lv_obj_set_style_pad_all(menu, 0, LV_PART_MAIN);
  lv_obj_set_flex_align(menu, LV_FLEX_ALIGN_START, LV_FLEX_ALIGN_CENTER, LV_FLEX_ALIGN_CENTER);
  lv_obj_set_scroll_dir(menu, LV_DIR_VER);
  lv_gridnav_add(menu, LV_GRIDNAV_CTRL_ROLLOVER);

  lv_obj_t *item1 = lv_obj_create(menu);
  lv_obj_set_size(item1, 300, 50);
  lv_obj_set_flex_flow(item1, LV_FLEX_FLOW_ROW);
  lv_obj_set_flex_align(item1, LV_FLEX_ALIGN_START, LV_FLEX_ALIGN_CENTER, LV_FLEX_ALIGN_CENTER);
  lv_obj_clear_flag(item1, LV_OBJ_FLAG_SCROLLABLE);

  lv_obj_t *label1 = lv_label_create(item1);
  lv_label_set_text(label1, "Item 1");
  lv_obj_set_flex_grow(label1, 5);
  lv_obj_t *sw1 = lv_switch_create(item1);
  lv_obj_remove_state(sw1, LV_STATE_FOCUSED);
  lv_obj_set_flex_grow(sw1, 1);

  lv_obj_t *item2 = lv_obj_create(menu);
  lv_obj_set_size(item2, 300, 50);
  lv_obj_set_flex_flow(item2, LV_FLEX_FLOW_ROW);
  lv_obj_set_flex_align(item2, LV_FLEX_ALIGN_START, LV_FLEX_ALIGN_CENTER, LV_FLEX_ALIGN_CENTER);
  lv_obj_clear_flag(item2, LV_OBJ_FLAG_SCROLLABLE);

  lv_obj_t *label2 = lv_label_create(item2);
  lv_label_set_text(label2, "Item 2");
  lv_obj_set_flex_grow(label2, 5);
  lv_obj_t *sw2 = lv_switch_create(item2);
  lv_obj_remove_state(sw2, LV_STATE_FOCUSED);
  lv_obj_set_flex_grow(sw2, 1);

Because the switch component is added to the default group, as the documentation says Switch (lv_switch) — LVGL documentation

LV_KEY_UP/RIGHT Turns on the slider
LV_KEY_DOWN/LEFT Turns off the slider
LV_KEY_ENTER Toggles the switch,
the keys only the toggle switch state, does not change the focused of the switch, so it only appears to correspond to the first switch.
i think should remove it from default group,and Use custom event callbacks to handle keystroke events.
