    components: {
      MDBAlert,
    },
  };
</script>
<script setup lang="ts">
  import { MDBAlert } from 'mdb-vue-ui-kit';
</script>

Additional Content

<template>
  <MDBAlert color="success" static>
    <h4 class="alert-heading">Well done!</h4>
    <p>
      Aww yeah, you successfully read this important alert message. This example text is
      going to run a bit longer so that you can see how spacing within an alert works with
      this kind of content.
    </p>
    <hr />
    <p class="mb-0">
      Whenever you need to, be sure to use margin utilities to keep things nice and tidy.
    </p>
  </MDBAlert>
</template>
<script>
  import { MDBAlert } from 'mdb-vue-ui-kit';
  export default {
    components: {
      MDBAlert,
    },
    setup() {},
  };
</script>
<script setup lang="ts">
  import { MDBAlert } from 'mdb-vue-ui-kit';
</script>

Dismissing

Using the Vue alert component, it’s possible to dismiss any alert inline. Here’s how:

  • Add a dismiss property, which adds close button and extra padding to the right of the alert which positions the close button.
  • Click on the close button to dismiss the alert.

You can see this in action with a live demo:

<template>
  <MDBAlert dismiss :autohide="false" color="warning" static v-model="alert9">
    <strong>Holy guacamole!</strong> You should check in on some of those fields below.
  </MDBAlert>
</template>
<script>
  import { MDBAlert } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';
  export default {
    components: {
      MDBAlert,
    },
    setup() {
      const alert9 = ref(true);
      return {
        alert9,
      };
    },
  };
</script>
<script setup lang="ts">
  import { MDBAlert } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';

  const alert9 = ref(true);
</script>

Show

You can manually show alert using show() method on the alert component ref.

<template>
  <MDBBtn color="primary" @click="hiddenAlertRef?.show()"> Show alert! </MDBBtn>
  <MDBAlert
    class="mt-3 text-center"
    color="primary"
    static
    hidden
    v-model="alert10"
    ref="hiddenAlertRef"
  >
    Hidden alert!
  </MDBAlert>
</template>
<script>
  import { MDBAlert, MDBBtn } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';
  export default {
    components: {
      MDBAlert,
      MDBBtn,
    },
    setup() {
      const hiddenAlertRef = ref(null);
      const alert10 = ref(false);

      return {
        hiddenAlertRef,
        alert10,
      };
    },
  };
</script>
<script setup lang="ts">
  import { MDBAlert, MDBBtn } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';

  const hiddenAlertRef = ref<InstanceType<typeof MDBAlert> | null>(null);
  const alert10 = ref(false);
</script>

Hide

You can manually hide alert using hide() method on alert component ref.

<template>
  <MDBBtn color="primary" @click="showAlertRef?.hide()"> Hide me! </MDBBtn>
  <MDBAlert
    class="text-center mt-3"
    color="primary"
    v-model="alert11"
    static
    :autohide="false"
    ref="showAlertRef"
  >
    Hide me!
  </MDBAlert>
</template>
<script>
  import { MDBAlert, MDBBtn } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';
  export default {
    components: {
      MDBAlert,
      MDBBtn,
    },
    setup() {
      const showAlertRef = ref(null);
      const alert11 = ref(true);

      return {
        showAlertRef,
        alert11,
      };
    },
  };
</script>
<script setup lang="ts">
  import { MDBAlert, MDBBtn } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';

  const showAlertRef = ref<InstanceType<typeof MDBAlert> | null>(null);
  const alert11 = ref(true);
</script>

Placement

You can set the position of every alert using the position property.

Select horizontal / vertical alignment

Current position: top-right
<template>
  <div class="text-center">
    <p class="fw-bold">Select horizontal / vertical alignment</p>
  </div>
  <div class="my-4 text-center">
    <MDBBtn color="primary" @click="setVertical('top')">Top</MDBBtn>
    <MDBBtn color="primary" class="ms-2" @click="setVertical('bottom')"> Bottom </MDBBtn>
  </div>
  <div class="my-4 text-center">
    <MDBBtn color="primary" @click="setHorizontal('left')">Left</MDBBtn>
    <MDBBtn color="primary" class="mx-2" @click="setHorizontal('center')">
      Center
    </MDBBtn>
    <MDBBtn color="primary" @click="setHorizontal('right')"> Right </MDBBtn>
  </div>
  <div class="mb-4 text-center">
    <h5>
      Current position:
      <span id="positionDisplay">{{ alert12position }}</span>
    </h5>
  </div>
  <MDBBtn color="primary" @click="alert12 = true"> Show! </MDBBtn>
  <MDBAlert
    v-model="alert12"
    width="250px"
    :position="alert12position"
    autohide
    appendToBody
    color="primary"

  import { ref, computed } from 'vue';
  export default {
    components: {
      MDBAlert,
      MDBBtn,
    },
    setup() {
      const alert12 = ref(false);
      const vertical = ref('top');
      const horizontal = ref('right');
      const alert12position = computed(() => {
        return `${vertical.value}-${horizontal.value}`;
      });
      const setHorizontal = (value) => {
        horizontal.value = value;
      };
      const setVertical = (value) => {
        vertical.value = value;
      };
      return {
        alert12,
        alert12position,
        setHorizontal,
        setVertical,
      };
    },
  };
</script>
<script setup lang="ts">
  import { MDBAlert, MDBBtn } from 'mdb-vue-ui-kit';
  import { ref, computed } from 'vue';

  const alert12 = ref(false);
  const vertical = ref('top');
  const horizontal = ref('right');
  const alert12position = computed(() => {
    return `${vertical.value}-${horizontal.value}`;
  });
  const setHorizontal = (value: string) => {
    horizontal.value = value;
  };
  const setVertical = (value: string) => {
    vertical.value = value;
  };
</script>

Container

You can display an alert anywhere. Just put it in your target element and fill the data-mdb-container attribute with id or class of parent. 

<template>
  <MDBContainer class="text-center" id="parent-container-example">
    <MDBBtn color="primary" class="mb-5" @click="alert13 = true">
      Show alert below!
    </MDBBtn>
    <MDBAlert
      v-model="alert13"
      autohide
      :delay="5000"
      position="top-right"
      stacking
      container="#parent-container-example"
      color="primary"
    >
      Hello from parent element!
    </MDBAlert>
  </MDBContainer>
</template>
<script>
  import { MDBAlert, MDBBtn, MDBContainer } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';
  export default {
    components: {
      MDBAlert,
      MDBBtn,
      MDBContainer,
    },
    setup() {
      const alert13 = ref(false);
      return {
        alert13,
      };
    },
  };
</script>
<script setup lang="ts">
  import { MDBAlert, MDBBtn, MDBContainer } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';

  const alert13 = ref(false);
</script>

Offset

You can set offset of your alert using a offset> property. 

<template>
  <MDBBtn color="primary" @click="alert14 = true"> Show alert with offset! </MDBBtn>
  <MDBAlert
    v-model="alert14"
    offset="100"
    autohide
    :delay="5000"
    position="top-right"
    width="250px"
    appendToBody
    color="primary"

    Offset: 100px
  </MDBAlert>
</template>
<script>
  import { MDBAlert, MDBBtn } from 'mdb-vue-ui-kit';
  import { ref } from 'vue';

Stacking - Container

You can also stack alerts inside the container

<template>
  <MDBContainer
  class="text-center"
  id="parent-stacking-container-example"
  >
    <MDBBtn color="primary" class="mb-5" @click="addStackingContainer">

CSS variables

As part of MDB’s evolving CSS variables approach, alerts now uses local CSS variables on .alert for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too. 

// .alert
--#{$prefix}alert-bg: transparent;
--#{$prefix}alert-padding-x: #{$alert-padding-x};
--#{$prefix}alert-padding-y: #{$alert-padding-y};
--#{$prefix}alert-margin-bottom: #{$alert-margin-bottom};
--#{$prefix}alert-color: inherit;
--#{$prefix}alert-border-color: transparent;
--#{$prefix}alert-border: #{$alert-border-width} solid var(--#{$prefix}alert-border-color);
--#{$prefix}alert-border-radius: #{$alert-border-radius};

// .alert-fixed
--#{$prefix}alert-fixed-z-index: #{$zindex-alert};

SCSS variables

$alert-zindex: 1070;

$alert-padding-y: 1.25rem;
$alert-padding-x: 1.5rem;
$alert-margin-bottom: 1rem;
$alert-border-radius: $border-radius-lg;
$alert-link-font-weight: $font-weight-bold;
$alert-border-width: $border-width;
$alert-bg-scale: -80%;
$alert-border-scale: -70%;
$alert-color-scale: 40%;
$alert-dismissible-padding-r: $alert-padding-x * 3;
