Pop up fields
The presentation configuration screen includes a tab labelled "Pop up fields".
Pop up fields are used where there is not enough space onscreen to display all of the details you may show users. Adding pop up fields will add a "Details / more information" icon in your display. Tapping on this icon will display a pop up window, which displays the additional information to the user.
If you have been changing labels / fields in the 'Display fields', please ensure you select 'Update' before switching tabs to 'Pop up fields'
Selecting which fields to use for pop up fields
Popup fields use exactly the same configuration procedure as "Display fields". As these will need to be configured first, please see the instructions on how to configure display fields in the Display fields how-to article. The same procedure can be followed, by selecting "Pop up fields" tab instead of "Display fields".
