Get label, Get owner

Hello, i check all the documentation but i didn’t see, how can i get on my web site, the select option for Label and Owner like this picture.


I create my form and i can send the Name and the Address but i cant send the label and the owner because i have to make a GET request.

Thanks for helping me, and sorry for my bad english.
