How the Material-UI Tooltip zIndex takes precedence over the MenuItem in the Select component

Question

How the Material-UI Tooltip zIndex takes precedence over the MenuItem in the Select component

My issue is quite straightforward. I have a <Tooltip> component wrapping a <Select> component, and when I click the Select, the tooltip appears above the MenuItems like this:

Expected behavior:

Unexpected behavior:

I kept all the default values for Material-UI, and for the Tooltip it's: zIndex: 1500, but there isn't one for MenuItem as far as I can tell. I tried setting the zIndex of MenuItem to 1501, but the behavior remained the same.

I am curious about the correct way to either position the tooltip behind the MenuItem or hide the tooltip altogether when the Select MenuItems are displayed...

Below is a snippet of my code:

<Tooltip title={'Filter by status'}>
    <Select value={this.state.status} onChange={this.handleChange.bind(this, Filter.Status)}>
        {statuses.sort(this.filterItemSortFn).map(item => {
            return (<MenuItem style={{zIndex: 1501}} value={item}>{item}</MenuItem>);
        })}
    </Select>
</Tooltip>

If I decrease the zIndex of the tooltip so that it hides behind the MenuItems, it works, but I prefer not to override default values as it may impact other zIndex settings.

Answer №1

Incorrectly, Liam's response does not match the requirements for MUI v4 while Joe's answer is irrelevant.

The z-index of the Tooltip component is inherited from the Popper component, meaning that altering the z-index exclusively for the Tooltip will yield no results. It is necessary to transmit the z-index from the Tooltip up to the Popper.

For example:

<Tooltip title={"foo"} PopperProps={{style:{zIndex:0}}}>

There was a known bug in the Material-Ui Tooltip, but it has been resolved in the latest version.

To resolve the issue, simply add a zIndex to your tooltip component:

<Tooltip title={"Message"} style={{ zIndex: '1' }}>
        <Select 
          value={this.state.name}
          onChange={this.handleChange}
          input={<Input id="select-multiple" />}
          MenuProps={MenuProps}
        >
          {names.map(name => (
            <MenuItem key={name} value={name}>
              {name}
            </MenuItem>
          ))}
        </Select>
      </Tooltip>

If you want to hide the tooltip completely when the menu is open, use the following code:

<Tooltip title={"Message"} 
            onClick={() => this.setState({ tooltip: !this.state.tooltip })}
          style={this.state.tooltip ? {display: 'none'}:{ zIndex: '1' }}>
            <Select 
              value={this.state.name}
              onChange={this.handleChange}
              input={<Input id="select-multiple" />}
              MenuProps={MenuProps}
            >
              {names.map(name => (
                <MenuItem key={name} value={name}>
                  {name}
                </MenuItem>
              ))}
            </Select>
          </Tooltip>

Make sure to define the tooltip state in your component:

class MultipleSelect extends React.Component {
  state = {
    name: [],
    tooltip: false,
  };
