i try to send a LV_KEY_RIGHT/DOWN LV_KEY_LEFT/UP LY_KEY_ENTER to a dropdown list，but it has no effect.
May I ask how to achieve this?
i try to do this again
it still has not effect.
I tried again for half a day。
group = lv_group_create();
This way it can move the selection of ddList , but it can not apply the selected option for
I tried something else in order to apply the selected option, but still no effect。
id = lv_dropdown_get_selected(ddlist); printf("selected id = %d", id); lv_dropdown_set_selected(ddlist, id); //unavailable id's value changed by move list,but invalid //lv_dropdown_set_selected(ddlist, 0); //avaliable Direct assignment is valid. lv_dropdown_close(ddlist);
i can already move dropdown list, so i want to apply the selected option。Through the above method,it still no effect。
