Yes, we suggest to use the iFame embed code as sometimes there may be some conflicts between the existing code on your website and the form's code.
This guide will help you to get the iFrame code of your form: Getting-the-form-iFrame-code
So you should embed your from like this:
height:2190px; <---- You will need to manually set the needed height value.
This should help you to avoid any conflict.
Hope this helps.
