While using Altru's membership web forms you may notice that the add to cart button overlaps over the membership add on button when you have 4 to 5 membership add-ons available online for your membership program. This issue only occurs when you're using responsive web forms.
We are currently evaluating this issue and will update this article when we have more information.
