### Dual thumb
|
||||
|
||||
Add `range` attribute to open dual thumb mode
|
||||
|
||||
```html
|
||||
<van-slider v-model="value" range @change="onChange" />
|
||||
```
|
||||
|

|
||||

|
||||
|
||||
export default {
|
||||
data() {
|
||||
return {
|
||||
// value must be an Array
|
||||
value: [10, 50],
|
||||
};

},
|
||||
methods: {

onChange(value) {

### Vertical, Dual thumb mode
|
||||
|
||||
Add `range` and `vertical` attributes at the same time, and make sure that the value of `value` is an array
|
||||
|
||||
```html
|
||||
<div :style="{ height: '120px' }">
