Progress

Use our custom progress component for displaying simple or complex progress bars, featuring support for horizontally stacked bars, animated backgrounds, and text labels.

<template>
  <div>
    <b-progress :value="counter" :max="max" show-progress animated></b-progress>
    <b-progress class="mt-1" :max="max" show-value>
      <b-progress-bar :value="counter*(6/10)" variant="success"></b-progress-bar>
      <b-progress-bar :value="counter*(2.5/10)" variant="warning"></b-progress-bar>
      <b-progress-bar :value="counter*(1.5/10)" variant="danger"></b-progress-bar>
    </b-progress>
    <b-btn class="mt-4" @click="clicked">Click me</b-btn>
  </div>
</template>

<script>
export default {
  data () {
    return {
      counter: 45,
      max: 100
    }
  },
  methods: {
    clicked () {
      this.counter = Math.random() * this.max
      console.log('Change progress to ' +
        Math.round(this.counter * 100) / 100)
    }
  }
}
</script>

<!-- progress-1.vue -->

Value

Set the maximum value with the max prop (default is 100), and the current value via the value prop (default 0).

When creating multiple bars in a sinple process, place hte value prop on the individual <b-progress-bar> sub components (see the Multiple Bars section below for more details)

Labels

Add labels to your progress bars by either enabling show-progress (percentage of max) or show-valuefor the current absolute value. You may also set the precision (number of digits after the decimal) via the precision prop (default is 0digits after the decimal).

<template>
  <div>
    <h5>No label</h5>
    <b-progress :value="value" :max="max" class="mb-3"></b-progress>
    <h5>Value label</h5>
    <b-progress :value="value" :max="max" show-value class="mb-3"></b-progress>
    <h5>Progress label</h5>
    <b-progress :value="value" :max="max" show-progress class="mb-3"></b-progress>
    <h5>Value label with precision</h5>
    <b-progress :value="value" :max="max" :precision="2" show-value class="mb-3"></b-progress>
    <h5>Progress label with precision</h5>
    <b-progress :value="value" :max="max" :precision="2" show-progress class="mb-3"></b-progress>
  </div>
</template>

<script>
export default {
  data () {
    return {
      max: 50,
      value: 33.333333333
    }
  }
}
</script>

<!-- progress-labels.vue -->

Custom progress label

Need more control over the label? Provide your own label by using the default slot within a <b-progress-bar> sub-component, or by using the label prop on <b-progress-bar> (HTML supported):

<template>
  <div>
    <h5>Custom Label via Default Slot</h5>
    <b-progress :max="max">
      <b-progress-bar :value="value">
        Progress: <strong>{{ value.toFixed(3) }} / {{ max }}</strong>
      </b-progress-bar>
    </b-progress>

    <h5 class="mt-3">Custom Label via Prop</h5>
    <b-progress :max="max">
      <b-progress-bar :value="value" :label="'&lt;'+value.toFixed(0)+'&gt;'">
      </b-progress-bar>
    </b-progress>
  </div>
</template>

<script>
export default {
  data () {
    return {
      max: 50,
      value: 33.333333333
    }
  }
}
</script>

<!-- progress-custom-labels.vue -->

Precedence order for label methods:

  • default slot of <b-progress-bar>
  • label prop of <b-progress-bar>
  • show-progress prop of <b-progress-bar>
  • show-value prop of <b-progress-bar>
  • show-progress prop of <b-progress>
  • show-value prop of <b-progress>
  • no label

Width and Height

<b-progress> will always expand to the maximum with of it's parent container. To change the width, place <b-progress> in a standard Bootstrap column or apply one of the standard Bootstrap width classes.

<template>
  <div>
    <h5>Default width</h5>
    <b-progress :value="value" class="mb-3"></b-progress>
    <h5>Custom widths</h5>
    <b-progress :value="value" class="w-75 mb-2"></b-progress>
    <b-progress :value="value" class="w-50 mb-2"></b-progress>
    <b-progress :value="value" class="w-25"></b-progress>
  </div>
</template>

<script>
export default {
  data () {
    return {
      value: 75
    }
  }
}
</script>

<!-- progress-width.vue -->

The height of the progress bar can be controled with the height prop. The height value should be a standard CSS dimension (px, rem, em, etc). The default height is 1rem.

<template>
  <div>
    <h5>Default height</h5>
    <b-progress :value="value" show-progress class="mb-3"></b-progress>
    <h5>Custom heights</h5>
    <b-progress height="2rem" :value="value" show-progress class="mb-2"></b-progress>
    <b-progress height="20px" :value="value" show-progress class="mb-2"></b-progress>
    <b-progress height="2px" :value="value"></b-progress>
  </div>
</template>

<script>
export default {
  data () {
    return {
      value: 75
    }
  }
}
</script>

<!-- progress-height.vue -->

Backgrounds

Use background variants to change the appearance of individual progress bars. The default variant is primary.

Solid background variants

<template>
  <div>
    <div v-for="bar in bars" class="row mb-1">
      <div class="col-sm-2">{{ bar.variant }}:</div>
      <div class="col-sm-10 pt-1">
        <b-progress :value="bar.value"
                    :variant="bar.variant"
                    :key="bar.variant"
        ></b-progress>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data () {
    return {
      bars: [
        {variant: 'success', value: 75},
        {variant: 'info', value: 75},
        {variant: 'warning', value: 75},
        {variant: 'danger', value: 75},
        {variant: 'primary', value: 75},
        {variant: 'secondary', value: 75},
        {variant: 'dark', value: 75}
      ],
      timer: null
    }
  },
  mounted () {
    this.timer = setInterval(() => {
      this.bars.forEach(bar => bar.value = 25 + (Math.random() * 75))
    }, 2000)
  },
  beforeDestroy () {
    clearInterval(this.timer)
    this.timer = null
  }
}
</script>

<!-- progress-backgrounds.vue -->

Striped backgrounds

Set striped to apply a stripe via CSS gradient over the progress bar’s background variant.

<template>
  <div>
    <b-progress :value="25" variant="success" :striped="striped" class="mb-2"></b-progress>
    <b-progress :value="50" variant="info" :striped="striped" class="mb-2"></b-progress>
    <b-progress :value="75" variant="warning" :striped="striped" class="mb-2"></b-progress>
    <b-progress :value="100" variant="danger" :striped="striped" class="mb-2"></b-progress>
    <b-button variant="secondary" @click="striped = !striped">
      {{ striped ? 'Remove' : 'Add'}} Striped
    </b-button>
  </div>
</template>

<script>
export default {
  data () {
    return {
      striped: true
    }
  }
}
</script>

<!-- progress-striped.vue -->

Animated backgrounds

The striped gradient can also be animated by setting the animatedprop.

<template>
  <div>
    <b-progress :value="25" variant="success" striped :animated="animate" class="mb-2"></b-progress>
    <b-progress :value="50" variant="info" striped :animated="animate" class="mb-2"></b-progress>
    <b-progress :value="75" variant="warning" striped :animated="animate" class="mb-2"></b-progress>
    <b-progress :value="100" variant="danger" :animated="animate" class="mb-3"></b-progress>
    <b-button variant="secondary" @click="animate = !animate">
      {{ animate ? 'Stop' : 'Start'}} Animation
    </b-button>
  </div>
</template>

<script>
export default {
  data () {
    return {
      animate: true
    }
  }
}
</script>

<!-- progress-animated.vue -->

Notes:

  • if animated is true, striped will automatically be enabled.
  • Animated progress bars don’t work in Opera 12 — as they don’t support CSS3 animations.

Multiple bars

Include multiple <b-progress-bar> sub-components in a <b-progress> component to build a horizontally stacked set of progress bars.

<template>
  <div>
    <b-progress :max="max" class="mb-3">
      <b-progress-bar variant="primary" :value="values[0]"></b-progress-bar>
      <b-progress-bar variant="success" :value="values[1]"></b-progress-bar>
      <b-progress-bar variant="info" :value="values[2]"></b-progress-bar>
    </b-progress>
    <b-progress show-progress :max="max" class="mb-3"></b-progress-bar>
      <b-progress-bar variant="primary" :value="values[0]"></b-progress-bar>
      <b-progress-bar variant="success" :value="values[1]"></b-progress-bar>
      <b-progress-bar variant="info" :value="values[2]"></b-progress-bar>
    </b-progress>
    <b-progress show-value striped :max="max" class="mb-3"></b-progress-bar>
      <b-progress-bar variant="primary" :value="values[0]"></b-progress-bar>
      <b-progress-bar variant="success" :value="values[1]"></b-progress-bar>
      <b-progress-bar variant="info" :value="values[2]"></b-progress-bar>
    </b-progress>
    <b-progress :max="max" class="mb-3">
      <b-progress-bar variant="primary" :value="values[0]" show-progress></b-progress-bar>
      <b-progress-bar variant="success" :value="values[1]" animated show-progress></b-progress-bar>
      <b-progress-bar variant="info" :value="values[2]" striped show-progress></b-progress-bar>
    </b-progress>
  </div>
</template>

<script>
export default {
  data () {
    return {
      max: 100,
      values: [ 15, 30, 20 ]
    }
  }
}
</script>

<!-- progress-multiple.vue -->

<b-prgress-bar> will inherit most of the props from the <b-progress> parent component, but you can override any of the props by setting them on the <b-progress-bar>

Notes:

  • height, if specified, should always set on the <b-progress> component.
  • <b-progress-bar> will not inherit value from <b-progress>.
