Issues with zDepth functionality in Material-UI (React.js) not being functional

Can anyone explain the concept of zDepth to me? I have a component with the following render method:

render() {
  return (
    <div>
      <AppBar
        zDepth={2}
        title="Some title"
        iconElementLeft={<IconButton onClick={this.handleToggle}><NavigationClose /></IconButton>}
      />
      <Drawer
        open={this.state.open}
        width={200}
        zDepth={1}>
        <MenuItem>Menu Item</MenuItem>
        <MenuItem>Menu Item 2</MenuItem>
      </Drawer>
    </div>
  )
}

I was expecting that the AppBar would be rendered in front of the Drawer, but it doesn't work that way:

See the result here.

Answer №1

zDepth won't be effective in this scenario. The drawer component has unique characteristics compared to other classic components. If you need your Appbar to always stay in front, you can implement the following solution as discussed in this thread:

Check out a live example here

render() {
  return (
    <div>
      <AppBar
        zDepth={2}
        title="Some title"
        iconElementLeft={<IconButton onClick={this.handleToggle}><NavigationClose /></IconButton>}
      />
      <Drawer
        open={this.state.open}
        width={200}
        zDepth={1}
        style={{ height: AppBar.height }}> // <== Make sure to place it here
        <MenuItem>Menu Item</MenuItem>
        <MenuItem>Menu Item 2</MenuItem>
      </Drawer>
    </div>
  )
}
