# Case fields

Cortex AgentiX includes out-of-the-box case fields, case fields from installed content packs, and user defined custom case fields. Case fields can be used for custom case layouts, and for display in the **Cases** table.

Custom case fields can be exported and imported. To export a single custom case field, right-click on the field in the fields table, and select **Export**. To export all custom case fields in a single JSON file, click the **Export All** button above the fields table. System case fields cannot be exported or imported.

After a custom case field is created, it can be edited, deleted, or exported by right-clicking on the row. The field name and field type cannot be changed after the field is created. System fields cannot be edited, deleted, or exported.

### Warning

Deleting a case field or uninstalling a content pack containing a case field may affect capabilities based on the deleted field and layouts.
{% endhint %}

## 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://cortex-docs.paloaltonetworks.com/cortex-agentix/configure-cortex-agentix/cases-and-issues-configuration/customize-case-fields-and-layouts/case-fields.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.
