Hi guys!
I have a question. I created 7 tabs in the tabview.
Seven buttons in tabview were created, and a blue box appeared in the button area. I want to get rid of this blue box, what should I do?

I solved it.
lv_obj_set_style_outline_width(tab_btns, 0, LV_PART_ITEMS | LV_STATE_FOCUS_KEY);
This way you can remove the outline of the tabview button matrix.
