Anchoring the portal to the base of page stretches fields inside (which is great). If you have the 'create new record row' at the base of the portal it become obscured. Does anyone know any workaround so that it is visible? (v12)

Actually on further investigation many rows are obscured.

I haven't tried this myself (don't use flexible layouts that often), but I remembered reading about anchors and portal resizing in FileMaker 10 Bible. Here's the passage:

“Additionally, portals exhibit different vertical resizing behavior depending on the anchor properties of the objects within them. If all the objects within a portal are anchored to the top (but not to the bottom) and the portal is anchored to top and bottom, when the portal height increases, it will display additional rows. However, if any items within the portal are anchored to the bottom and/or not anchored to the top (that is, set to move or resize vertically), the portal rows will increase in height rather than number: The number of rows will remain constant, and their sizes will increase proportionally as the portal is enlarged.”

So it seems that some nifty object configuration allows you to choose between larger rows or more rows. Hope this helps.

I understand the principal and the stretching (where the field increases in height) works as advertised except the bottom rows become inaccessible. Seems to be a bug, so would be interested to see if others have the same issue.
