Tooltip

Display prompt information for mouse hover.

Basic usage

Tooltip has 9 placements.

:::demo Use attribute content to set the display content when hover. The attribute placement determines the position of the tooltip. Its value is [orientation]-[alignment] with four orientations top, left, right, bottom and three alignments start, end, null, and the default alignment is null. Take placement="left-end" for example, Tooltip will display on the left of the element which you are hovering and the bottom of the tooltip aligns with the bottom of the element.

<el-tooltip content="Bottom center" placement="bottom" effect="light">
  <el-button>Light</el-button>
</el-tooltip>

:::

More Content

Display multiple lines of text and set their format.

:::demo Override attribute content of el-tooltip by adding a slot named content.

<el-tooltip placement="top">
  <div slot="content">multiple lines<br/>second line</div>
  <el-button>Top center</el-button>
</el-tooltip>

Advanced usage

In addition to basic usages, there are some attributes that allow you to customize your own:

transition attribute allows you to customize the animation in which the tooltip shows or hides, and the default value is el-fade-in-linear.

disabled attribute allows you to disable tooltip. You just need set it to true.

In fact, Tooltip is an extension based on Vue-popper, you can use any attribute that are allowed in Vue-popper.

:::demo

<template>
  <el-tooltip :disabled="disabled" content="click to close tooltip function" placement="bottom" effect="light">
    <el-button @click="disabled = !disabled">click to {{disabled ? 'active' : 'close'}} tooltip function</el-button>
  </el-tooltip>
</template>

<script>
  export default {
    data() {
      return {
        disabled: false
      };
    }
  };
</script>

<style>
  .slide-fade-enter-active {
    transition: all .3s ease;
  }
  .slide-fade-leave-active {
    transition: all .3s cubic-bezier(1.0, 0.5, 0.8, 1.0);
  }
  .slide-fade-enter, .expand-fade-leave-active {
    margin-left: 20px;
    opacity: 0;
  }
</style>
