Tooltip

<mo-tooltip> | MOTooltip
Since 1.0 stable

Tooltips display additional information based on a specific action.

A tooltip’s target is its first child element, so you should only wrap one element inside of the tooltip. If you need the tooltip to show up for multiple elements, nest them inside a container first.

Tooltips use display: contents so they won’t interfere with how elements are positioned in a flex or grid layout.

Hover Me 
<mo-tooltip content="This is a tooltip">
  <mo-button>Hover Me</mo-button>
</mo-tooltip>

import { MOButton, MOTooltip } from '@metsooutotec/modes-web-components/dist/react';

const App = () => (
  <MOTooltip content="This is a tooltip">
    <MOButton>Hover Me</MOButton>
  </MOTooltip>
);

Examples

Click trigger

Set the trigger attribute to click to toggle the tooltip on click instead of hover.

Click to Toggle 
<mo-tooltip content="Click again to dismiss" trigger="click">
  <mo-button>Click to Toggle</mo-button>
</mo-tooltip>

import { MOButton, MOTooltip } from '@metsooutotec/modes-web-components/dist/react';

const App = () => (
  <MOTooltip content="Click again to dismiss" trigger="click">
    <MOButton>Click to Toggle</MOButton>
  </MOTooltip>
);

Manual trigger

Tooltips can be controller programmatically by setting the trigger attribute to manual. Use the open attribute to control when the tooltip is shown.

Toggle Manually 
<mo-button style="margin-right: 4rem;">Toggle Manually</mo-button>

<mo-tooltip content="This is an avatar" trigger="manual" class="manual-tooltip">
  <mo-avatar></mo-avatar>
</mo-tooltip>

<script>
  const tooltip = document.querySelector('.manual-tooltip');
  const toggle = tooltip.previousElementSibling;

  toggle.addEventListener('click', () => (tooltip.open = !tooltip.open));
</script>

import { useState } from 'react';
import { MOAvatar, MOButton, MOTooltip } from '@metsooutotec/modes-web-components/dist/react';

const App = () => {
  const [open, setOpen] = useState(false);

  return (
    <>
      <MOButton style={{ marginRight: '4rem' }} onClick={() => setOpen(!open)}>
        Toggle Manually
      </MOButton>

      <MOTooltip open={open} content="This is an avatar" trigger="manual">
        <MOAvatar />
      </MOTooltip>
    </>
  );
};

HTML in tooltips

Use the content slot to create tooltips with HTML content. Tooltips are designed only for text and presentational elements. Avoid placing interactive content, such as buttons, links, and form controls, in a tooltip.

I’m not just a tooltip, I’m a tooltip with HTML!
Hover me 
<mo-tooltip>
  <div slot="content">I'm not <strong>just</strong> a tooltip, I'm a <em>tooltip</em> with HTML!</div>

  <mo-button>Hover me</mo-button>
</mo-tooltip>

import { MOButton, MOTooltip } from '@metsooutotec/modes-web-components/dist/react';

const App = () => (
  <MOTooltip content="This is a tooltip">
    <div slot="content">
      I'm not <strong>just</strong> a tooltip, I'm a <em>tooltip</em> with HTML!
    </div>

    <MOButton>Hover Me</MOButton>
  </MOTooltip>
);

Hoisting

Tooltips will be clipped if they’re inside a container that has overflow: auto|hidden|scroll. The hoist attribute forces the tooltip to use a fixed positioning strategy, allowing it to break out of the container. In this case, the tooltip will be positioned relative to its containing block, which is usually the viewport unless an ancestor uses a transform, perspective, or filter. Refer to this page for more details.

No Hoist Hoist 
<div class="tooltip-hoist">
  <mo-tooltip content="This is a tooltip">
    <mo-button>No Hoist</mo-button>
  </mo-tooltip>

  <mo-tooltip content="This is a tooltip" hoist>
    <mo-button>Hoist</mo-button>
  </mo-tooltip>
</div>

<style>
  .tooltip-hoist {
    border: solid 2px var(--mo-panel-border-color);
    overflow: hidden;
    padding: var(--mo-spacing-medium);
    position: relative;
  }
</style>

import { MOButton, MOTooltip } from '@metsooutotec/modes-web-components/dist/react';

const css = `
  .tooltip-hoist {
    border: solid 2px var(--mo-panel-border-color);
    overflow: hidden;
    padding: var(--mo-spacing-medium);
    position: relative;
  }
`;

const App = () => (
  <>
    <div class="tooltip-hoist">
      <MOTooltip content="This is a tooltip">
        <MOButton>No Hoist</MOButton>
      </MOTooltip>

      <MOTooltip content="This is a tooltip" hoist>
        <MOButton>Hoist</MOButton>
      </MOTooltip>
    </div>

    <style>{css}</style>

disabled Disables the tooltip so it won’t show when triggered. boolean false
distance The distance in pixels from which to offset the tooltip away from its target. number 8
open Indicates whether or not the tooltip is open. You can use this in lieu of the show/hide methods. boolean false
skidding The distance in pixels from which to offset the tooltip along its target. number 0
