According to https://ux.stackexchange.com/a/38982/111876, I don't need to display the current selected language option because the UI already provided this information. But I found it is difficult to display the language selector without current selected language, for example:
Case 1: Display other available language
I found it looks like telling user that this page is written in Es currently.
Case 2: use ----- :
It seems look even worse because I believe users would have no idea what ----- is. So my question is, if current language option is not required to show, how to I display the language selector?
