Create FirstComponent.vue and import it into App.js

Create the new component in the src/components/ components folder. the component name is FirstComponent.vue and imported into the App.js file:

App.js

<template>
  <div id="app">
    <FirstComponent />
  </div>
</template>

<script>
import FirstComponent from "./components/FirstComponent.vue";
export default {
  name: "App",
  components: {
    FirstComponent,
  },
};
</script>

Unchecked all checkboxes

To add the checkbox we are going to use the form checkbox <b-form-checkbox> component. these components <b-form-checkbox-group> and <b-form-checkbox> use the bootstrap custom checkbox input to replace the browser default checkbox input.so it is a solid replacement for the default checkbox input. Let’s see the code example:

FirstComponent.js

<template>
  <div id="app">
    <b-form-group>
      <template #label>
        <b>Choose your Days:</b><br />
        <b-form-checkbox
          v-model="allSelected"
          :indeterminate="indeterminate"
          aria-describedby="days"
          aria-controls="days"
          @change="unCheckedAll"
        >
          {{ allSelected ? "Un-select All" : "Select All" }}
        </b-form-checkbox>
      </template>

      <template v-slot="{ ariaDescribedby }">
        <b-form-checkbox-group
          id="flavors"
          v-model="selected"
          :options="days"
          :aria-describedby="ariaDescribedby"
          name="flavors"
          class="ml-4"
          aria-label="Individual days"
          stacked
        ></b-form-checkbox-group>
      </template>
    </b-form-group>

    <div>
      Selected: <strong>{{ selected }}</strong
      ><br />
      All Selected: <strong>{{ allSelected }}</strong
      ><br />
      Indeterminate: <strong>{{ indeterminate }}</strong>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      days: ["Monday", "Tuesday", "Wednesday", "Friday", "Sunday"],
      selected: [],
      allSelected: false,
      indeterminate: false,
    };
  },
  methods: {
    unCheckedAll(checked) {
      this.selected = checked ? this.days.slice() : [];
    },
  },
  watch: {
    selected(newValue, oldValue) {
      if (newValue.length === 0) {
        this.indeterminate = false;
        this.allSelected = false;
      } else if (newValue.length === this.flavours.length) {
        this.indeterminate = false;
        this.allSelected = true;
      } else {
        this.indeterminate = true;
        this.allSelected = false;
      }
    },
  },
};
</script>

For now, let’s check the output.
