# Checkmarks

Checkmarks can be edited on a per-UI state basis. The options available to customize in checkmarks are: default, checked and disabled. 

These are used in [select](/adding-questions-and-content/question-reference/select.md) questions when **Show checkmarks and radio buttons on choices** is enabled in the question's settings, and in [confirm](/adding-questions-and-content/question-reference/confirmation.md) content types.

### Styling

In the **Theme** -> **Checkmarks** section, you have two checkmark options: single choice (radio) and multiple choice (box).&#x20;

* **Multiple choice** will be used on any Select questions with "Allow multiple selection" **enabled**.
* **Single choice** will be used when the above setting is disabled.&#x20;

{% hint style="info" %}
The Select questions will also need **Show checkmarks and radio buttons on choices** enabled as well.&#x20;
{% endhint %}

Please refer to our [CSS reference](/css-and-advanced-styling/css-reference.md) section for more information on the style properties that can be adjusted in this menu.&#x20;

## 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.formsort.com/styling/customizing-appearance/checkmarks.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.
