Hi Hosein,
Thanks so much for your report!
I reproduced the issue with RTL and added it to our bug tracker. It’s basically the same issue as reported by yourself here: SOLVED: Bug in accordion element (in RTL) - #2 by timmse
You can easily fix it in the meantime with the following to get the same default styling as in LTR:
%root% li {
margin: 0;
}
However, I can’t replicate any issue with LTR
Best regards,
timmse
