Repeated section (master-detail / data band)

A SectionSchema is a plain rectangle — it holds no children, it's just a group: any field (text, image, table) dropped on top of it on the canvas becomes a member (via BaseSchema.sectionId), while staying a normal field in the flat template.schemas array — same absolute position, same way to select/edit/drag. Dragging a field OUT of the section clears the link again (bidirectional).

A section only drags by its purple bar at the top — clicking anywhere else on it (or a field on top of it) selects normally, without moving it.

Once bound

Once bound (type: "section", path to the array), the section repeats once per item of the array — stacking vertically and paginating together with the rest of the body.

Inside it:

• Any member text resolves {field} against the current item (not the whole document), and {Line}/{index} gives the repetition number (1, 2, 3…).
• A member table with no binding of its own shows a single row, cell by cell, against the current item — an empty cell falls back to the column name directly (head[i] → {item[head[i]]}), a filled-in cell is a real template.
• A member table WITH an array binding (a path relative to the item — e.g. Order → OrderItems) is real master-detail: one row per item of the nested array, and the section grows in height to fit (text below the table, if any, shifts down with it).

A section can also have zero tables — just member text fields is already a valid repeated "record"/list.
