Make all item visible through API before form submit

Hey, thanks for the great plugin you've been developing. I 've been reading the docs and looking into source for a while, but I could not find a way to make all items visible at a time. I have inputs in all pages and I need them to get submitted along with the form, but only the inputs of the active page are being submitted. One workaround could be set pagination to "view all" before form submit, but I do not let my users change the number of items per page, so I got no select/dropdown to do so. How can I acomplish that with API call and/or jQuery? Thank you!
