Looking for a way to do something like this:
I know of a few methods to do this, but have not found the "silver bullet" yet:
1) A layout switch with portals above and below: most commonly used, but an annoying setup with 2 duplicate layouts to manage - I am not that committed, although I love the idea.
2) Sub-Summary part - This has the most potential (after you work out the field-setting and sorting), but you always end up with an extra sub-summary part above or below. This seems possibly acceptible for the simplicity...perhaps a script to hide the record detail when the user scrolls up or down? (thus revealing your secret!)
Anyone have a solid solution I have not thought of? Perhaps one day FileMaker will add some "tree" and "detail" functions to portals...until then we come up with tricky solutions.
