Due to the complexity of case report forms in clinical trials, TrialKit provides an automated tool for study builders to take a form they've built and rapidly set it up for multiple devices, and still maintain a streamlined dataset single set of data in the end.
The steps below outline how to target form layout for multiple devices. These steps only apply to study builders.
Ensure you have access to the Device Dictionary within the Host Configuration menu on the app. If you don't see it, contact support@trialkit.com to have it enabled.

2. Setup the device target Targeted Device sizes or PDFs that will be needed in the study.
It's okay if you are not sure about which screen sizes to target, especially for ePRO studies where subjects use their own devices. Having 3-5 targeted sizes for a range of devices is sufficient.

When defining the screen width value of different devices, TrialKit uses what is called UIKit sizes (or points), based on pixel mapping used by iOS. You can read more here on that.
...
Notice in the form above, it was set with a width of 1400. This is likely because other tabs on the form include content that takes up more width on a screen and is designed to be completed on the website.
Scroll to the bottom of the form properties and select a device to target. The list of options is the one from step 2 above. There is also an option to force the layout into a single column if desired. Depending on the screen width and current form layout, this may happen anyway.
Then tap the Build Device Form button.

In the background, the system will instantaneously re-arrange the form layout to fit the device width being targeted. The new form referred to as a child (targeted) form, that was created can be accessed in the Form Manager screen. It will have the same name as the parent form followed by a number. You will also see a description of the device it's targeted for.

change the layout or item sizes as desired, and save the changes.

Important: Do not change any of the fields, add fields, add new or delete fields on a child form. If a change must be made to something other than the layout form variables or field sizeslogic, make the change on the parent form and then re-create the targeted form . |
At any time, you can open the form manager's list of forms and easily differentiate between parent and child forms.
Child forms are simply a re-arranged version of the main/parent form.

If changes need to be made to the content of a form - such as adding edit checks, or changing questions, delete the child forms associated with that form, make the changes in the parent form, and repeat the steps above to quickly re-create the child forms. |

so the form variables and behavior match. Form Targeting should only be used to alter the layout of forms for different presentation. |
