# Radio
|
|
|
|
Single selection among multiple options.
|
|
|
|
### Basic usage
|
|
|
|
Radio should not have too many options. Otherwise, use the Select component instead.
|
|
|
|
:::demo Creating a radio component is easy, you just need to bind a variable to Radio's `v-model`. It equals to the value of `label` of the chosen radio. The type of `label` is `String`, `Number` or `Boolean`.
