You want a catalog, directory, or price list where entries flow across pages and the document grows to fit your data – not one fixed page repeated.
In InDesign, build the layout block for one entry on the pasteboard – outside any page. This block is the repeating unit DataMergeStudio flows onto the pages.

The master pages must contain primary text frames. As content fills, DataMergeStudio adds pages from the master spread, and your entries flow through these primary text frames.

Switch to the Editor and set up Layout Flow: select the layout block(s) you built and the order they should flow in.

In the same place where you select the layout blocks, you can add a break. Choose whether the break comes before every block or once before a new group of blocks, and pick the type: Page Break, Column Break, or Frame Break.

Still in the node editor, connect each field of your entry to its data column, exactly as in a normal merge.

Open Export → Merge Mode and select Flow. Flow becomes available once your layout is compatible – the indicator in the Layout area tells you when it is.

Open the Preview (the eye icon, top right) to check the result, then click Validate all records (the button in the bottom-right corner of the workspace) before exporting a long document.

A flowing, multi-page publication composed from your data – pages added as needed, sections breaking exactly where you want them.
