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.

<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.

<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.

<template>
  <el-button @click="add">Add Item</el-button>
  <el-button @click="delete">Delete Item</el-button>
  <el-scrollbar max-height="400px">
    <p class="item" v-for="item in count">{{ item }}</p>
  </el-scrollbar>
</template>

<script>
  export default {
    data() {
      return {
        count: 3
      }
    },
    methods: {
      add() {
        this.count++
      },
      delete() {
        if (this.count > 0) {
          this.count--
        }
      }
    }
  }
</script>

:::demo Use setScrollTop and setScrollLeft methods can control scrollbar manually.

<template>
  <el-scrollbar ref="scrollbar" height="400px" always>
    <div ref="inner">
      <p class="item" v-for="item in 20">{{ item }}</p>
    </div>

        max: 0,
        value: 0
      }
    },
    mounted() {
      this.max = this.$refs.inner.clientHeight - 380
    },
    methods: {
      inputSlider(value) {
        this.$refs.scrollbar.setScrollTop(value)
