# Board Filters

Board filters let people narrow what a board shows — by date, location, provider, campaign, or any other dimension — without editing a single widget.

## Ask AskCorral to build one for you

You don't need to build filters by hand. Just tell AskCorral (or Claude/ChatGPT, if you've connected the CorralData MCP server) what you want to filter by, and it'll set it up on the board for you:

* "Add a location filter to the Sales board"
* "Filter this board by campaign name, using the campaign column in the ad spend table"
* "Update the date filter on this board to default to the last 30 days"
* "Remove the provider filter from this board"

AskCorral creates, updates, and removes board filters directly — no need to configure a query or pick options yourself. If you want a filter to apply to specific widgets only, mention that and AskCorral will scope it accordingly.

{% hint style="info" %}
Prefer to describe what you want in plain language rather than SQL — AskCorral will translate it into the right filter configuration.
{% endhint %}

## How filters work

* Filters can be **static** (a fixed list of options you provide) or **dynamic** (options pulled live from a column in your data).
* A filter can apply to one board or several.
* Once added, a filter shows up as a dropdown or control at the top of the board for anyone viewing it.

## Removing a filter

Ask AskCorral to remove it, e.g. "Remove the region filter from this board" — or reach out to <support@corraldata.com> if you'd like help.

## 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.corraldata.com/kb/organize-your-data/board-filters.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.
