# Create a list

To create a Text, Markdown, HTML, CSS, or JSON list type:

1. Go to Settings → Configurations → Object Setup → Lists → Add a List.
2. Enter a name for the list.
3. From the list, select the Content Type.
4. Set Permissions for the list. By default, all roles can read and edit the list. You can instead choose specific roles to have read only or read and edit access.

   If you intend to use the list as part of an Automation Exclusion Policy, we recommend choosing specific roles for read and edit access. For more information on using lists in exclusion policies, see [Manage automation exclusion policies](/cortex-xdr-5.x/detect-investigate-and-respond-to-threats/investigate-and-respond-to-cases/automation/manage-automation-exclusion-policies.md).
5. Add content as required. For an example of a JSON list and how to use it, see [Use cases: JSON lists](/cortex-xdr-5.x/detect-investigate-and-respond-to-threats/investigate-and-respond-to-cases/automation/lists/use-cases-json-lists.md).
6. To save, do one of the following:
   * Click Save.
   * Click Save Version to save your changes in Version history for all Lists. This allows you to revisit and restore previous versions.

If you want to edit a list from a content pack, you need to duplicate or detach a list. Detached lists do not receive updated content in subsequent Cortex XDR content releases. To retain an updated list, reattach it.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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-xdr-5.x/detect-investigate-and-respond-to-threats/investigate-and-respond-to-cases/automation/lists/create-a-list.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.
