Translate menu?

Hi.
Sorry, but i do not understand what exactly you mean.

My menu on the left, can that be tranlated with the plugin?

From dutch to french

Sure.
Please navigate to Categories admin page.
You will be able to set different text for each language in the same way you do it in posts.

I don’t mean the names of the pages, but the actual MENU LINKS, you see on the left on my website

You can not change captions in menu editor, but you could translate pages/categories/posts names.
These names will not be displayed in the right way at admin part ( look here: https://c2n.me/iv70mm ) but they will on a site.

I just want to say that menu items text depend on pages/categories/posts names.

Ok thanks,

Is there any way i can get a (short)code to put the widget in the header?

Yes
<?php if ( function_exists( 'ztrans_generateLanguageSelectCode' ) ) ztrans_generateLanguageSelectCode( 'image' ); ?>

The translation on the pages doesn’t work for some reason.

If you could help me out on this one .. ?

Could you describe your problem?
What exactly doesn’t work? Do language selection buttons appear on page edit page?

The language buttons appear yes.

But when i fill in the french text, it stays in dutch on frontend, nothing happens.

Also changing page names to french, does not change on front end.

If you need more information, let me know

Any further help on this matter?

Please open a console (Press F12 in browser) and check if there are any JS errors.
Does it works on posts pages?

Don’t see any js errors

Please have a look for yourself, that may be easier and faster, no?
