Registration multiple Multi Dropdown List

Hi guys!

I have a couple of questions regarding the registration form.

First: In the registration form I have setted a multi dropdown list where my users can select the languages they speak (image1), I would like to know if I can add another multi dropdown where they can add the speak level of each of the languages they speak, just like in the advanced search module (image2)

Second: I have setted another multi dropdown list for my users where they can pick their country, is it possible to attach an image to each country? I would like to display the flag of their country in their profile details.

Thank you so much!
