Tooltip

Tooltips display informative text when users hover over, focus on, or tap an element.

When activated, Tooltips display a text label identifying an element, such as a description of its function.

Simple Tooltips

<Tooltip title="Delete">
  <IconButton aria-label="delete">
    <DeleteIcon />
  </IconButton>
</Tooltip>
<Tooltip title="Add" aria-label="add">
  <Fab color="primary" className={classes.fab}>
    <AddIcon />
  </Fab>
</Tooltip>
<Tooltip title="Add" aria-label="add">
  <Fab color="secondary" className={classes.absolute}>
    <AddIcon />
  </Fab>
</Tooltip>

Positioned Tooltips

The Tooltip has 12 placements choice. They don’t have directional arrows; instead, they rely on motion emanating from the source to convey direction.

Customized tooltips

Here are some examples of customizing the component. You can learn more about this in the overrides documentation page.

Arrow Tooltips

You can use the arrow prop to give your tooltip an arrow indicating which element it refers to.

<Tooltip title="Add" arrow>
  <Button>Arrow</Button>
</Tooltip>

Custom child element

The tooltip needs to apply DOM event listeners to its child element. If the child is a custom React element, you need to make sure that it spreads its properties to the underlying DOM element.

const MyComponent = React.forwardRef(function MyComponent(props, ref) {
  //  Spread the props to the underlying DOM element.
  return <div {...props} ref={ref}>Bin</div>
});

// ...

<Tooltip title="Delete">
  <MyComponent>
</Tooltip>

You can find a similar concept in the wrapping components guide.

Triggers

You can define the types of events that cause a tooltip to show.

Controlled Tooltips

You can use the open, onOpen and onClose properties to control the behavior of the tooltip.

<Tooltip open={open} onClose={handleClose} onOpen={handleOpen} title="Add">
  <Button>Controlled</Button>
</Tooltip>

Variable Width

The Tooltip wraps long text by default to make it readable.

<Tooltip title={longText}>
  <Button className={classes.button}>Default Width [300px]</Button>
</Tooltip>
<Tooltip title={longText} classes={{ tooltip: classes.customWidth }}>
  <Button className={classes.button}>Custom Width [500px]</Button>
</Tooltip>
<Tooltip title={longText} classes={{ tooltip: classes.noMaxWidth }}>
  <Button className={classes.button}>No wrapping</Button>
</Tooltip>

Interactive

A tooltip can be interactive. It won't close when the user hovers over the tooltip before the leaveDelay is expired.

<Tooltip title="Add" interactive>
  <Button>Interactive</Button>
</Tooltip>

Disabled Elements

By default disabled elements like <button> do not trigger user interactions so a Tooltip will not activate on normal events like hover. To accommodate disabled elements, add a simple wrapper element, such as a span.

⚠️ In order to work with Safari, you need at least one display block or flex item below the tooltip wrapper.

<Tooltip title="You don't have permission to do this">
  <span>
    <Button disabled>A Disabled Button</Button>
  </span>
</Tooltip>

If you're not wrapping a Material-UI component that inherits from ButtonBase, for instance, a native <button> element, you should also add the CSS property pointer-events: none; to your element when disabled:

<Tooltip title="You don't have permission to do this">
  <span>
    <button disabled={disabled} style={disabled ? { pointerEvents: "none" } : {}}>
      {'A disabled button'}
    </button>
  </span>
</Tooltip>

Transitions

Use a different transition.

<Tooltip title="Add">
  <Button>Grow</Button>
</Tooltip>
<Tooltip TransitionComponent={Fade} TransitionProps={{ timeout: 600 }} title="Add">
  <Button>Fade</Button>
</Tooltip>
<Tooltip TransitionComponent={Zoom} title="Add">
  <Button>Zoom</Button>
</Tooltip>

Showing and hiding

The tooltip is normally shown immediately when the user's mouse hovers over the element, and hides immediately when the user's mouse leaves. A delay in showing or hiding the tooltip can be added through the properties enterDelay and leaveDelay, as shown in the Controlled Tooltips demo above.

On mobile, the tooltip is displayed when the user longpresses the element and hides after a delay of 1500ms. You can disable this feature with the disableTouchListener property.

<Tooltip title="Add" enterDelay={500} leaveDelay={200}>
  <Button>[500ms, 200ms]</Button>
</Tooltip>
