Thanks for your reply. I've checked your Website on mobile screen size and are you saying that you want the flag to be next to each other as shown in the attached screenshot?
The flag is already showing without a dropdown as shown in the attached screenshot. Probably you figured it out.
As for the language switcher on the "mobile header", it looks like it is displayed using Elementor. I've made some adjustments for you voluntarily and could you please check?
