Hi @muhammad.abdullah,
Thank you for reaching out! 
Regarding the incorrect input field styling, please note that setting the width to 100% will adjust the plugin element to fill the entire width of the parent group. To ensure this works as expected, kindly double-check the width settings of the parent group in the layout tab. Additionally, although plugin element dimensions can be modified in the layout tab, please keep in mind that certain styling aspects, such as font size, are configured within the plugin’s settings. These internal style settings affect the appearance of the input value itself.

For the missing country flags in the dropdown, I tested the latest plugin version (1.94.0) on both our demo page and my personal page, and I wasn’t able to replicate the issue you described. Could you please confirm the version you’re currently using? If an update is available, please go ahead and update, as this may resolve the issue.

Additionally, feel free to visit our demo page and compare your setup with ours—it may help identify any discrepancies.
Looking forward to your reply. 
Best regards,
Mina
