# Partitioning

Instead of assigning every map item to a container by hand, a container can be set to **Auto partitioning mode**. Sollumz then splits the items assigned to it into auto-generated child containers, following the same conventions as the vanilla game maps:

* entities and car generators (*strm*),
* entities with large LOD distances (*long*),
* entities marked as critical (*critical*),
* interiors (*milo*),
* and grass.

Large sets are further split into numbered chunks by position.

LOD entities stay in the Auto container itself, which acts as the LOD parent YMAP.

Partitions are regenerated with the Generate Partitions button, or automatically on export if new items were added since.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sollumz.org/documentation/maps/partitioning.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
