Unselected elements in form

Hello guys, again rs

1- How can i not display the false atributes in my form?

In lockers, when i send my form. Everything thats not select came to my email as “false”. And have a lot of information to look. I only want that came the “true” atributes. Have a better way to do it?

2- Another thing, how can i not show the select field in the form, when it not been selected?

3- Aaaand, what is “custom atributes”?

4- Thanks!!!

Anyone have some idea what to do? Or maybe is a bug in my browser?

I receive that list, and have another items that i dont have to receive (more 160 entries saying false), and the lockers without information that i have not selected.

tks!!!
