Can you describe in more detail what you are trying to accomplish? Off hand what you want may well not be possible in FileMaker.
In my present edit box, I have a scrollable display that should the label on the left and the text answer for the right. I was interested in adding a possible row which would display an image thumbnail.
But this does not require putting all this data in a single field.
This can be three separate fields in a row and multiple rows can be displayed as a list view, table view or in a portal.
Merge fields can be use with list view and portals if you want to "close up" the space separating the fields due to differences in the amount of text in each field.
