# Drilldown views
When you filter a view by a "view tag", you create a parent/child relationship between views. We display this relationship using nested views, which you can see in the side navigation menu.
Nested views are a simple way to build robust, specific analysis across views.
### Shortcut: Create a view from tag
When highlights are grouped by tag, you can quickly create a nested view filtered by that tag by selecting the group's action menu > Create view from tag
### Examples of when you might use nest views:
* **Split up large groups**: sometimes views with a lot of data can cluster into large groups. Discover more themes by drilling down into these larger groups
* **Use the assistant**: if you want the assistant to focus on a specific theme it's helpful to filter by only that theme.
Remember: As new data is added to folders, classification views can continue tagging uncategorized highlights, making nested views all the more valuable!

## 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://help.getcustomeriq.com/product-guides/reports/drilldown-views.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.
