Your research is correct and complete. You can shrink fields but not expand them for print/preview purposes. This can be irritating as MS Access has had this capability for years. To get the needed results in FileMaker, you need to use one layout for data entry and another layout for printing. In the Print layout, you then make the field larger than you ever expect to need and set it to slide up and to resize the enclosing part. You also will need to do this for all objects next to and below that field that are in the same layout part--including graphic objects such as a horizontal line.
Key facts about sliding layout objects:
- It's only visible in preview mode and when you print/save as PDF...
- Sliding fields will shrink but not expand.
- All layout objects below and in the same layout part as the slide/resize field need to also be set to slide up and resize.
- Objects in headers and footers will not slide.
- Portals will shrink/slide to fit the number of rows of records, but fields within the portal row will not shrink/slide.
- Fields will slide up only if Top alignment is specified for it and will slide left only if Left alignment is specified.
- Consistent side borders are difficult to achieve with sliding fields.
- In FMP13, hidden objects (”Hide object when”) will slide/resize.
Sadly yes, a smaller object wont grow larger. Usually you make the text box large enough to accommodate the largest amount of text. Then using 'sliding up' and 'also resize enclosing part'. The sliding will only appear in Preview Mode, and when you print. For this reason it may be easier to have the layout you work with/enter data with the smaller text box and scroll bar, and a separate layout for printing that has the larger text box and sliding.
