Implemented the flags. Works fine. Tks.
I modified your code to add a alt="{{ language.title }} in the <img>
tag so that the language will still be visible when pictures are
hidden.
But in the admin > add, I cannot find the Cantonese language in the
menu... Only Chinese (code ZH).
Cantonese is the official Language in Hong Kong and Macau and is
spoken in Hong Kong, Macau, Guangdong Province, China and widely
spoken in overseas Chinese communities. That is about 70 million
people, more than each of Polish, Romanian, Dutch, Thai, ...
languages...
Would be nice to add.
Anyway, I use ZH first.
