        that it would work correctly?I attach the the lyx 2.0 file (MWE).Thanks,bcsikosThe problem seems to be that the "nosep" option for the enumeration
    is in the wrong place. It might be getting crosswise with the
    language changes. I got it to compile as follows.I removed the magyar option from the line in the preamble that
        loads babel. This may not be necessary for you, but on my system
        "magyar" is not recognized by babel as a language name.I deleted the "enumerate options" inset.I put the cursor at the start of item 1 and hit enter,
        temporarily changing the text to item 2.In the new (empty) item 1 (which has reverted to English), I
        used Insert > Enumerate Options to add back the "nosep"
        option, then put the cursor after the inset and hit delete to
        bring the original text back to item 1.HTH,PaulHello:Adding an option to enumitem in lyx 2.3.6. doesn't work if the list item has different language than the previous text. It works in lyx 2.0.6. It is a regression. I attach lyx, exported latex and compiled pdf files created with lyx 2.0.6 and 2.3.6.1.bcsikos
