Iframe and excerpt not working

Hello,

I am working with SiteOrigin page builder and it is just awesome. Thanks for such a nice product.

Now I am trying to create some custom widgets for my theme and I got some problems as mentioned below :
1. I can not save iframe code with tinymce and textarea in custom widget.
2. If I use the_excerpt() or the_content() in template with post type in form, live editor stops working.

Please help me out.

Looking forward to hear from experts.

Many Thanks Beforehand !
