# Intro
Actor tags are still quite common in Unreal engine, there are really useful for instance to [filter out actors](https://dev.epicgames.com/documentation/en-us/unreal-engine/finding-actors-in-unreal-engine#getspecificactorswithtag), in blueprint or [pcg graphs](https://dev.epicgames.com/documentation/en-us/unreal-engine/procedural-content-generation-framework-node-reference-in-unreal-engine#filter).\
\
Compared to [Gameplay tags](https://dev.epicgames.com/documentation/en-us/unreal-engine/using-gameplay-tags-in-unreal-engine), they are simple strings that you can add or remove from actors ( or components ). This is quite error prone, as a simple typo can break your systems.\
\
This utility widget allows you to create libraries of tags and assign and remove them with just a click.\
There is also a system of callbacks, when you assign or remove a tag, an editor utility blueprint function can be automatically executed to have custom post processes.

### Features:

**Settings**
Various settings are available on tags and libraries. Such as "hidden" parameter, or "deprecated" to prevent a tag to be assigned, but still shown in the list of tags ( to quickly see if this deprecated tag is still in use in the level ).

## 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://cgtoolbox.gitbook.io/cgtoolbox-docs/actor-tags-manager/intro.md?ask=&goal=
```
`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.
