I'm using Vuetify and trying to keep the v-tooltip open when mouse is hovering over the "tooltip". The content inside the tooltip is going to be rich and don't want that to automatically hide when visitor is looking into it.

<template>
<v-tooltip
  v-model="show"
  max-width="600px"
  content-class="link-tooltip-content"
  bottom>
  <template v-slot:activator="{ on }">
    <div
      :style="boxStyle"
      @mouseover="mouseover"
      @mouseleave="mouseleave"
    ></div>
  </template>
  <template v-slot:default>
    <v-card
      @mouseover="mouseover"
      @mouseleave="mouseleave"
      >
      <v-row dense>
        <v-col>
          <v-card-title class="headline">
            rich tooltip
          </v-card-title>
        </v-col>
      </v-row>
    </v-card>
  </template>
</v-tooltip>
</template>

<script>
    export default {
  data: () => ({
    show: false,
    hoverTimer: null
  }),
  methods: {
    boxStyle: function() {
      return {
        left: "100px",
        top: "100px",
        width: "100px",
        height: "100px",
        position: "absolute"
      };
    },
    mouseover: function() {
      console.log(`mouseover`);
      this.show = true;
      clearTimeout(this.hoverTimer);
    },
    mouseleave: function() {
      console.log(`mouseleave`);
      this.hoverTimer = setTimeout(() => {
        this.show = false;
      }, 3000);
    }
  }
};
</script>

But this doesn't work. The mouseover and mouseleave event handlers on the activator slot (the "link") element does fire, but the event handlers on the default slot (the "tooltip") don't fire.

I think the reason is, because the content inside the "tooltip" is moved to somewhere else under the body tag.

The questions is, how can I keep the "tooltip" open when hovering over it.

I'm moving the mouse like this:

1. Hover over the link (the tooltip shows up).
2. Move the mouse out of the link and into the tooltip. (The link and tooltip is a few pixels apart) Now the mouseleave event for the link fires, and I want to add a mouseenter event handler on the tooltip. How do I do that ?

I'm thinking to add an mouseenter event on the tooltip, so that I can clearTimeout(hoverTimer) and keep the tooltip open.

I know there's a similar question from 9 years ago, using jQuery Keep tooltip opened when the mouse is over it , but I don't want to use jQuery if possible. I prefer a Vue way.

Here's a little reproducible example:

Instead of using v-tooltip, I suggest you use v-menu with the open-on-hover props set to true. If you have to nudge whatever you put in the menu, make sure to set an appropriate close-delay value, so the menu doesn't close before the user reaches it.

Example: https://codepen.io/stephane303/pen/WNwdNxY

    <v-menu open-on-hover right offset-x nudge-right="20" close-delay="100">

.v-tooltip__content has pointer-events:none set in vuetify.min.css. If you set it back to auto you allow it to be hovered.

When its hovered, its parent is hovered. And when its parent is hovered, it has a tooltip. So all you need is:

.v-tooltip__content {
  pointer-events: auto;
}

I made extended version of VTooltip for this purpose. Just pass interactive prop. See working example here by hovering Governance stepper: https://tzkt.io
