Language selection when adding content

I'm looking for a solution that would allow the choice of language in which the content is added to the website. Eg. Adding a blog in English, and choose the language option when adding a blog -> Language: English

Currently on my website I have only 2 languages and depends on me to the main page don't mix. I would like to separate them. Please help. Is there any solution for this?

This sort of request require too many changes to get a solution in the forum. You will need to get it done as a custom job.

I attach a screenshot, maybe now it will be more clear:

I have this for my news module. Members can select the language and add the news items.

Then when members have selected the dutch language as site language they will only get the dutch news items and not the english ones... (unless they change the site language again to EN)

 Great idea! Content on website doesn't have to be in one language. This option should be in each module.
The only question is difficult to do so...

Yes I agree. And it's not that difficult to do as long as they use a standard for all mods!!
And you can use that filter also on timeline and outline so people should have a choice in what language the items are visible. That i why i have build my own outline filter per mod group and language example: view photos only posted in Dutch.
or view news items posted in English.

Or you can just use Google translation on your website and write in any language you like and read it in your own. Just saying

 the translator is an option too

It's like the open cart software. You can choose the language you want to add the content in. You can even make the translations at the same time.

Same system as in the email templates where you can add content in different languages.

I think this is only needed for title and description. Everything else will change if you change the default language.

 Sorry but I am not interested Google translate, etc. (most professional websites that are not used).
Just what solusoft and I wrote and presented a screenshot interests me. I am surprised that it's so difficult to do ..it should be a basic feature in Dolphin for all modules.

 Do you know how to do it?
