Problems working with multiple forms (to front end posting) in the same page

Hi, I have problems working with multiple forms (to front end posting) in the same page. I use the front end plugin and ask this question to the developer:

I like to know If I load the form with ajax or inside an iframe to solve this, and how to do this.

Thanks
