Recursive Classification

Recursive classification lets you apply a classification level to a page and all of its sub-pages in one operation.

How to use it

1. Click the byline badge on the parent page.
2. Click Change Classification.
3. Select the target level.
4. Toggle Apply to all sub-pages. The dialog shows how many sub-pages will be updated.
5. Click Apply.

Only sub-pages that currently have a different classification are updated. Pages already at the target level are skipped.

Synchronous vs. asynchronous

The app automatically chooses the processing mode based on the number of pages:

Pages to update	Mode	Behavior
Up to 50	Synchronous	Processed immediately, result shown in the dialog
More than 50	Asynchronous	Parent page classified immediately, sub-pages processed in the background

Asynchronous processing

For large page trees, the app:

1. Classifies the parent page immediately.
2. Queues the remaining sub-pages for background processing.
3. Shows a progress bar with an estimated time of arrival.
4. You can close the dialog - processing continues in the background.
5. Re-open the dialog on the same page to see current progress.

Progress updates appear every 10 pages. When complete, the dialog shows the final count of classified and failed pages.

Timeout handling

Synchronous processing has a 20-second time limit. If the operation times out (e.g. on a large tree that was underestimated), the app reports how many pages were classified and how many remain. You can re-run the operation to continue where it left off.

Reclassification

Administrators can also reclassify all pages at a given level to a different level - for example, when removing or renaming a level. This is available in the global Configuration under the Levels tab and uses the same asynchronous processing pipeline.
