# Checkbox
|
|
|
|
A group of options for multiple choices.
|
|
|
|
## Basic usage
|
|
|
|
Checkbox can be used alone to switch between two states.
|
|
|
|
:::demo Define `v-model`(bind variable) in `el-checkbox`. The default value is a `Boolean` for single `checkbox`, and it becomes `true` when selected. Content inside the `el-checkbox` tag will become the description following the button of the checkbox.

|
|
|
## Disabled State
|
|
|
|
Disabled state for checkbox.
|
|
|
|
:::demo Set the `disabled` attribute.
|
|
|
|

|
|
## Checkbox group
|
|
|
|
It is used for multiple checkboxes which are bound in one group, and indicates whether one option is selected by checking if it is checked.
|
|
|
|
:::demo `checkbox-group` element can manage multiple checkboxes in one group by using `v-model` which is bound as an `Array`. Inside the `el-checkbox` element, `label` is the value of the checkbox. If no content is nested in that tag, `label` will be rendered as the description following the button of the checkbox. `label` also corresponds with the element values in the array. It is selected if the specified value exists in the array, and vice versa.

## Indeterminate
|
|
|
|
The `indeterminate` property can help you to achieve a 'check all' effect.
|
|
|
|
:::demo

|
|
|
## Minimum / Maximum items checked
|
|
|
|
The `min` and `max` properties can help you to limit the number of checked items.
|
|
|
|
:::demo
|
|
|
|
checkbox/limitation
|
|
|
|
:::
|
|
|
|
## Button style
|
|
|
|
Checkbox with button styles.
|
|
|
|
:::demo You just need to change `el-checkbox` element into `el-checkbox-button` element. We also provide `size` attribute.
