# Multiselect

**Form item name:** This is the name that the encompassing form will use to access the output of the checkbox. See [Custom Form](/app-builder/app-construction/elements/form-elements/custom-form.md) for how it's used.

**Options:** Each option has 2 input boxes. The upper box holds the actual value the checkbox takes (that will be able to be used from the output array) and the lower box holds the display name of that checkbox.

**Default value:** Select which option will be the default value.

**Multiple limit:** Maximum options a user will be able to select.

See [Form Check](/app-builder/app-construction/elements/form-check.md) for data validation.

See [Tooltip](/app-builder/app-construction/elements/tooltip.md) for tooltip configurations.

## Output

Like checkbox, the output of a multiselect will be an **array**.  For example, if you select option2 and option3, the form item will be `['option2', 'option3']`.&#x20;

## Supported Events

1. Change value: triggered when users change the selection.

## 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.acho.io/app-builder/app-construction/elements/form-elements/multiselect.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.
