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.

checkbox/basic

:::

Disabled State

Disabled state for checkbox.

:::demo Set the disabled attribute.

checkbox/disabled

:::

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.

checkbox/grouping

:::
