Drag the slider within a fixed range.

Basic usage

The current value is displayed when the slider is being dragged.

:::demo Customize the initial value of the slider by setting the binding value.

<template>
  <div class="block">
    <span class="demonstration">Default value</span>
    <el-slider v-model="value1"></el-slider>
  </div>
  <div class="block">
    <span class="demonstration">Customized initial value</span>
    <el-slider v-model="value2"></el-slider>
  </div>
  <div class="block">
    <span class="demonstration">Hide Tooltip</span>
    <el-slider v-model="value3" :show-tooltip="false"></el-slider>
  </div>
  <div class="block">
    <span class="demonstration">Format Tooltip</span>
    <el-slider v-model="value4" :format-tooltip="formatTooltip"></el-slider>
  </div>
  <div class="block">
    <span class="demonstration">Disabled</span>
    <el-slider v-model="value5" disabled></el-slider>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value1: 0,
        value2: 50,
        value3: 36,
        value4: 48,
        value5: 42
      }
    },
    methods: {
      formatTooltip(val) {
        return val / 100;
      }
    }
  }
</script>

The options can be discrete.

:::demo Set step size with the step attribute. You can display breakpoints by setting the show-stops attribute.

<template>
  <div class="block">
    <span class="demonstration">Breakpoints not displayed</span>
    <el-slider
      v-model="value1"
      :step="10">
    </el-slider>
  </div>
  <div class="block">
    <span class="demonstration">Breakpoints displayed</span>
    <el-slider
      v-model="value2"
      :step="10"
      show-stops>
    </el-slider>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value1: 0,
        value2: 0
      }
    }
  }
</script>

Slider with input box

Set value via a input box.

:::demo Set the show-input attribute to display an input box on the right.

<template>
  <div class="block">
    <el-slider
      v-model="value"
      show-input>
    </el-slider>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value: 0
      }
    }
  }
</script>

:::

Range selection

Selecting a range of values is supported.

:::demo Setting the range attribute activates range mode, where the binding value is an array made up of two boundary values.

<template>
  <div class="block">
    <el-slider
      v-model="value"
      range
      show-stops
      :max="10">
    </el-slider>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value: [4, 8]
      }
    }
  }
</script>

:::

Vertical mode

:::demo Setting the vertical attribute to true enables vertical mode. In vertical mode, the height attribute is required.

<template>
  <div class="block">
    <el-slider
      v-model="value"
      vertical
      height="200px">
    </el-slider>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value: 0
      }
    }
  }
</script>

:::

Show marks

:::demo Setting this marks attribute can show mark on slider.

<template>
  <div class="block">
    <el-slider
      v-model="value"
      range
      :marks="marks">
    </el-slider>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value: [30, 60],
        marks: {
          0: '0°C',
          8: '8°C',
          37: '37°C',
          50: {
            style: {
              color: '#1989FA'
            },
            label: this.$createElement('strong', '50%')
          }
        }
      }
    }
  }
