On the Form Properties tab, select Scale Viewport to Screen Size for all forms intended to be used via mobile devices. For all newly created form templates, this option is selected by default.
Design the form vertically to be consistent with mobile design practices. Mobile forms will function properly on a desktop, so designing forms with mobile functionality in mind keeps administrators from having to recreate the forms in the future.
Text boxes set to a display size larger than a mobile device screen are automatically scaled to the full size of the mobile device screen.
Tables and nested tables do not respond properly on mobile devices. To simulate tables, add a panel inside a repeating section. Multiple vertically-oriented columns can be added, but it is a best practice to only use one or two columns. A single, horizontally-oriented column wraps the text boxes when needed, making the column more responsive to a mobile device's resolution.
Stand-alone panels should be five columns or fewer in width and take into consideration the length of the data being entered into the field.
If a large amount of data is anticipated for a single field, it is a best practice to insert a multiline text box with the Automatically Expand Height option selected.
To prevent users from needing to scroll back to the top of the form to change pages, it is a best practice to create a custom action that creates a condition button a user can click to automatically navigate to the first field on the next page of the form.
Radio button groups wrap when appropriate and are spaced differently when rendered in a mobile environment.
The drawing control is not supported on mobile devices.
Images do not scale on mobile devices. If you use an image control, verify that the image being used cooperates with the mobile device's resolution.
It is a best practice to always test your forms before publishing them. The test drive functionality simulates rendering when reducing the size of the test drive window. If possible, test the forms using multiple devices on multiple operating systems by using shared forms.
