Tooltip

A tooltip is an informative message that appears when a user hovers over, focuses on, or taps an element, providing additional context, guidance, or information without cluttering the interface.

Simple tooltip.

<KTooltip text="Simple tooltip.">
  <InfoIcon />
</KTooltip>

Props

text

Text to display in the tooltip.

You will receive a notification once your request is approved.

<KTooltip text="You will receive a notification once your request is approved.">
  <KButton>Request</KButton>
</KTooltip>

When using the text prop (or the content slot), passing a value of undefined, an empty string, or no content slot content will prevent the tooltip from showing, while still displaying your default slot content.

<KTooltip :text="tooltipText">
  <KButton>My tooltip text is empty</KButton>
</KTooltip>

<script setup lang="ts">
import { ref } from 'vue'

// The tooltip doesn't have text yet,
// so hovering over the button will not render an empty tooltip
const tooltipText = ref<string>('')
</script>
