Progressbar Vue Component

<template>
  <f7-page>
    <f7-navbar title="Progress Bar"></f7-navbar>
    <f7-block>
      <p>
        In addition to <a href="/preloader/">Preloader</a>, Framework7 also comes with fancy
        animated determinate and infinite/indeterminate progress bars to indicate some activity.
      </p>
    </f7-block>
    <f7-block-title>Determinate Progress Bar</f7-block-title>
    <f7-block strong-ios outline-ios>
      <p>
        When progress bar is determinate it indicates how long an operation will take when the
        percentage complete is detectable.
      </p>
      <p>Inline determinate progress bar:</p>
      <div>
        <p><f7-progressbar id="demo-inline-progressbar" :progress="10" /></p>
        <f7-segmented raised>
          <f7-button @click="setInlineProgress(10)">10%</f7-button>
          <f7-button @click="setInlineProgress(30)">30%</f7-button>
          <f7-button @click="setInlineProgress(50)">50%</f7-button>
          <f7-button @click="setInlineProgress(100)">100%</f7-button>
        </f7-segmented>
      </div>
      <div>
        <p>Inline determinate load & hide:</p>
        <p id="demo-determinate-container"></p>
        <p>
          <f7-button fill @click="showDeterminate(true)">Start Loading</f7-button>
        </p>
      </div>
      <div>
        <p>Overlay with determinate progress bar on top of the app:</p>
        <p>
          <f7-button fill @click="showDeterminate(false)">Start Loading</f7-button>
        </p>
      </div>
    </f7-block>
    <f7-block-title>Infinite Progress Bar</f7-block-title>
    <f7-block strong>
      <p>
        When progress bar is infinite/indeterminate it requests that the user wait while something
        finishes when it’s not necessary to indicate how long it will take.
      </p>
      <p>Inline infinite progress bar</p>
      <p>
        <f7-progressbar infinite />
      </p>
      <p>Multi-color infinite progress bar</p>
      <p>
        <f7-progressbar infinite color="multi" />

      <div>
        <p>Overlay with infinite progress bar on top of the app</p>
