Embedded form jumps down when filled on iPhone

Есть еще одна проблема, на iphone когда заполняю форму full, она прыгает
вниз, когда я ввожу в графу количество грамм и приbr/>одится прокручивать
вверbr/> и искать эту строку, br/>отя вставлен код, где прописано nojump

Please give us more details so we can check the issue.

What is the URL of the form? Is it this form https://form.jotformeu.com/63264340056349
Is the form embedded here? http://mix.mueslimix.com.ua/ (FULL)

I was not able to replicate the issue in iPhone.

If you are still having issues, I suggest you redirect the users to the standalone version of the form instead of lightbox embed.
If you redirect the users to the Form URL, the form will perform better (faster) and the issue with the form jumping should disappear.
