What MCU/Processor/Board and compiler are you using?

ESP32C3 / arduino

What LVGL version are you using?

V8 last version (before V9)

What do you want to achieve?

To use properly the widget MENU

I feel I don’t open / close it properly (I’m using hidden flag)

I don’t find how to “reset” it

What have you tried so far?

I use a button to unhide the widget MENU

I try to clear and hidde it when I’m in a sub-menu, but it stays in sub menu

Thanks in advance for your help

Regards

Nobody know how to show / close a menu widget ?

Hidden it is it the good way to do it ?

I also use lv_obj_clear_flag(mymenu, LV_OBJ_FLAG_HIDDEN); to show menu. To hide menu I use lv_obj_add_flag(menu, LV_OBJ_FLAG_HIDDEN); inside back_event_handler() where I check lv_menu_back_btn_is_root(menu, obj). And this is works for me.

@glory-man thanks for you reply :slight_smile:

I do the same, so it seems it make sens !

How do you do when you hide the menu and you are in sub-menu ?
Like “resetting” the widget to go back to the main menu.

Thanks for your help

In my app I can leave menu only on the top level - when back button pressed. So I can’t leave menu in sub-menu.
