Summary
On the original Google Form, many of the last few questions allow users to select multiple options. While Android has a "checkbox" input option, we would like to implement a "multi-select" input field. This would be a spinner element that allows the user to continuously select items. They should be able to select as well as de-select items.
Current Behavior
Currently, when an item is selected on a spinner, that becomes the input selection. If another option is selected, it switches the input to that.
Benefits (Why is it necessary?)
Checkboxes are not the most user-friendly option on a mobile device. While android does have nice modern slide-button check boxes, the Registration form has far too many multi-selects with far too many options. The screen would become very cluttered, causing lots of scrolling and confusion for the user.
