I dont know if you guys will understand, but let me try explain:
The user gonna make youtr login, and there have a custon post called "Build", there he can insert: title, Description, Started Item (here my question)...
So in "Started Item", i wanna make a list of images he can select, like options.
So the user select how many he want and click on "OK" and its done, he can go to next step to post.
Someone have any idea how can i do it?
