## Scrollbar
|
||
|
|
|
||
|
|
Used to replace the browser's native scrollbar.
|
||
|
|
|
||
|
|
### Basic usage
|
||
|
|
|
||
|
|
:::demo Use `height` property to set the height of the scrollbar, or if not set, it adapts according to the parent container height.
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-scrollbar height="400px">
|
||
|
|
<p class="item" v-for="item in 20">{{ item }}</p>
|
||
|
|
</el-scrollbar>
|
||
|
|
```
|
||
|
|
|
||
|
|
:::
|
||
|
|
|
||
|
|
### Horizontal scroll
|
||
|
|
|
||
|
|
:::demo When the element width is greater than the scrollbar width, the horizontal scrollbar is displayed.
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-scrollbar>
|
||
|
|
<div class="flex-content">
|
||
|
|
<p class="item" v-for="item in 50">{{ item }}</p>
|
||
|
|
</div>
|
||
|
|
</el-scrollbar>
|
||
|
|
```
|
||
|
|
|
||
|
|
:::
|
||
|
|
|
||
|
|
### Max height
|
||
|
|
|
||
|
|
:::demo The scrollbar is displayed only when the element height exceeds the max height.
|
||
|
|
|
||
|
|
```html
|
||
|
|
<template>
|
||
|
|
<el-button @click="add">Add Item</el-button>
