# Multiselect

Multiselect allows you to select multiple options.

**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.
