# Yes/no (Boolean)

Use a **Yes/no** field for simple yes-or-no states such as approved, active, or complete.

For the general settings all data fields have in common, see [Shared field settings](/builder-hub/design-your-app/add-and-edit-data-fields-in-your-tables/all-data-fields/shared-field-settings.md).

Field-specific settings for **Yes/no** or **Boolean** are:

<i class="fa-memo">:memo:</i> **General**

* **Default value**: preselects the initial yes-or-no state for new records

<i class="fa-airplay">:airplay:</i> **Display**

* **Display as**: shows the options as **Checkbox**, **Dropdown**, **Switch**, or **Tabs**

We recommend using **Default value** to make filters and conditions easier to handle in automations. A default value ensures new records start as either "yes" or "no", instead of remaining empty.\
Without a default value, the field can have three states: "yes", "no", or "empty".\
For example, if you filter for `field_value = false`, records with an empty value are not included, even though users may treat them as no.

## 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.ninox.com/builder-hub/design-your-app/add-and-edit-data-fields-in-your-tables/all-data-fields/yes-no-boolean.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.
