Code to reproduce

static lv_style_t lv_style_dd;
static lv_style_t lv_style_dd_sel;

lv_style_init(&lv_style_dd);
lv_style_set_radius(&lv_style_dd, 5);
lv_style_set_bg_opa(&lv_style_dd, LV_OPA_100);
lv_style_set_bg_color(&lv_style_dd, GUI_COLOR_PURPLE);
lv_style_set_border_color(&lv_style_dd, GUI_COLOR_DARK_PURPLE);
lv_style_set_border_width(&lv_style_dd, 1);
lv_style_set_text_font(&lv_style_dd, &ampli_16);
lv_style_set_text_color(&lv_style_dd, GUI_COLOR_WHITE);
//lv_style_set_text_opa(&lv_style_dd, LV_OPA_COVER);

lv_style_init(&lv_style_dd_sel);
lv_style_set_radius(&lv_style_dd_sel, 0);
lv_style_set_bg_opa(&lv_style_dd_sel, LV_OPA_100);
lv_style_set_bg_color(&lv_style_dd_sel, GUI_COLOR_PURPLE);
lv_style_set_border_color(&lv_style_dd_sel, GUI_COLOR_DARK_PURPLE);
lv_style_set_border_width(&lv_style_dd_sel, 1);
lv_style_set_text_font(&lv_style_dd_sel, &ampli_16);
lv_style_set_text_color(&lv_style_dd_sel, GUI_COLOR_WHITE);
lv_style_set_text_opa(&lv_style_dd_sel, LV_OPA_COVER);

/Create a normal drop down list/
lv_obj_t* dd = lv_dropdown_create(parent);
lv_dropdown_set_options(dd,
“MM:DD:YY\n”
“DD:MM:YY\n”
“YY:MM:DD”
);

lv_obj_align(dd, LV_ALIGN_TOP_RIGHT, -5, 5);
//lv_obj_set_size(dd, 140, 35);
lv_obj_set_style_bg_color(dd, GUI_COLOR_PURPLE, 0);
lv_obj_set_style_border_color(dd, GUI_COLOR_DARK_PURPLE, 0);
lv_obj_set_style_text_color(dd, GUI_COLOR_WHITE, 0);
lv_obj_set_style_bg_color(dd, GUI_COLOR_PURPLE, LV_PART_ITEMS);

lv_obj_add_event_cb(dd, date_format_event_cb, LV_EVENT_VALUE_CHANGED, NULL);

lv_obj_t* list = lv_dropdown_get_list(dd);
//lv_obj_remove_style_all(list);
lv_obj_add_style(list, &lv_style_dd, LV_PART_MAIN);
lv_obj_add_style(list, &lv_style_dd_sel, LV_PART_SELECTED | LV_STATE_CHECKED | LV_STATE_PRESSED);

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.
