## Vertical Direction
Set `direction` to `vertical` to arrange slides vertically.
```html
<wd-swiper
:list="swiperList"
direction="vertical"
indicatorPosition="right"
autoplay
v-model:current="current"
:indicator="{ type: 'dots-bar' }"
@click="handleClick"
@change="onChange"
></wd-swiper>
```
## Custom Indicator
Use the `indicator` slot to customize the indicator style.
```html
<wd-swiper
:list="swiperList"
direction="vertical"
indicatorPosition="right"
autoplay
v-model:current="current"
@click="handleClick"
@change="onChange"
>
<template #indicator="{ current, total }">
<view class="custom-indicator" style="position: absolute; bottom: 24rpx; right: 24rpx">{{ current + 1 }}/{{ total }}</view>
</template>
</wd-swiper>
```
```scss
.custom-indicator {
padding: 0 12rpx;
height: 48rpx;
line-height: 48rpx;
border-radius: 45%;
background: rgba(0, 0, 0, 0.6);
color: #ffffff;
font-size: 24rpx;
}
```
## Specify valueKey and textKey
Use `value-key` to specify the image address field in each object of the `list`, default is `value`.
Use `text-key` to specify the title field in each object of the `list`, default is `text`.
```html
<wd-swiper
value-key="url"
text-key="title"
:list="customSwiperList"
autoplay
v-model:current="current"
@click="handleClick"
@change="onChange"
></wd-swiper>
```
```ts
const current = ref<number>(0)
const customSwiperList = ref([
{ url: 'https://wot-ui.cn/assets/redpanda.jpg', title: 'Red Panda!' },
{ url: 'https://wot-ui.cn/assets/capybara.jpg', title: 'Capybara!' },
{ url: 'https://wot-ui.cn/assets/panda.jpg', title: 'Giant Panda!' },
{ url: 'https://wot-ui.cn/assets/moon.jpg', title: 'Poetic China!' }
])
```
## Property Control Switching
```html
<wd-swiper :loop="isLoop" :autoplay="false" :list="swiperList" v-model:current="current" />
<wd-gap />
<wd-cell-group>
<wd-cell title="loop">
<wd-switch v-model="isLoop" size="24px" />
</wd-cell>
<wd-cell title="current" :value="current.toString()" />
</wd-cell-group>
<view style="display: flex; justify-content: space-between">
<wd-button @click="current--">prev</wd-button>
<wd-button type="success" @click="current++">next</wd-button>
</view>
```
```javascript
const current = ref<number>(0)
const isLoop = ref(false)
```
## Slot Usage
Use the default slot to customize the content of carousel items.
```html
<wd-swiper
:list="swiperList"
autoplay
v-model:current="current"
:indicator="{ type: 'dots-bar' }"
@click="handleClick"
@change="onChange"
>
<template #default="{ item }">
<image :src="item as string" mode="aspectFill" style="width: 100%; height: 100%" />
</template>
</wd-swiper>
```
