Material UI is a Material Design library made for React.
It’s a set of React components that have Material Design styles.
In this article, we’ll look at how to add dialog boxes with Material UI.
Dialog
A dialog box is used to let users know about some information.
To add one, we can use the Dialog component.
For example, we can write:
import React from "react";
import Button from "@material-ui/core/Button";
import Dialog from "@material-ui/core/Dialog";
import DialogTitle from "@material-ui/core/DialogTitle";
import List from "@material-ui/core/List";
import ListItem from "@material-ui/core/ListItem";
export default function App() {
const [open, setOpen] = React.useState(false);
const handleClose = () => {
setOpen(false);
};
return (
<div>
<Button variant="outlined" color="primary" onClick={() => setOpen(true)}>
Open simple dialog
</Button>
<Dialog onClose={handleClose} open={open}>
<DialogTitle id="simple-dialog-title">dialog</DialogTitle>
<List>
<ListItem autoFocus button onClick={handleClose}>
close
</ListItem>
</List>
</Dialog>
</div>
);
}
to add a dialog with some items in it.
We added a List with a ListItem which is a button.
We can click it to close the dialog box with the setOpen function with the false argument.
Then open prop controls whether it’s opened or not.
handleClose lets us close the dialog by setting open to false with setOpen .
variant set to outlined lets us add an outline.
Alerts
Alerts are used for display urgent messages.
To add one, we can use the components that we have before and add the DialogContent , DialogContentText , and DialogActions components to add the dialog content.
For example, we can write:
import React from "react";
import Button from "@material-ui/core/Button";
import Dialog from "@material-ui/core/Dialog";
import DialogTitle from "@material-ui/core/DialogTitle";
import DialogContent from "@material-ui/core/DialogContent";
import DialogContentText from "@material-ui/core/DialogContentText";
import DialogActions from "@material-ui/core/DialogActions";
export default function App() {
const [open, setOpen] = React.useState(false);
const handleClose = () => {
setOpen(false);
};
return (
<div>
<Button variant="outlined" color="primary" onClick={() => setOpen(true)}>
Open simple dialog
</Button>
<Dialog open={open} onClose={handleClose}>
<DialogTitle>Confirm</DialogTitle>
<DialogContent>
<DialogContentText>Are you sure?</DialogContentText>
</DialogContent>
<DialogActions>
<Button onClick={handleClose} color="primary">
no
</Button>
<Button onClick={handleClose} color="primary" autoFocus>
yes
</Button>
</DialogActions>
</Dialog>
</div>
);
}
to add everything.
DialogTitle has the title.
DialogContent has the content.
DialogContentText is where we put the text for the dialog.
DialogActions has the buttons to let users do something.
Transitions
We can add transition effects to animate when dialogs open.
For example, we can write:
import React from "react";
import Button from "@material-ui/core/Button";
import Dialog from "@material-ui/core/Dialog";
import DialogTitle from "@material-ui/core/DialogTitle";
import DialogContent from "@material-ui/core/DialogContent";
import DialogContentText from "@material-ui/core/DialogContentText";
import DialogActions from "@material-ui/core/DialogActions";
import Slide from "@material-ui/core/Slide";
const Transition = React.forwardRef((props, ref) => {
return <Slide direction="down" ref={ref} {...props} />;
});
export default function App() {
const [open, setOpen] = React.useState(false);
const handleClose = () => {
setOpen(false);
};
return (
<div>
<Button variant="outlined" color="primary" onClick={() => setOpen(true)}>
Open simple dialog
</Button>
<Dialog
open={open}
onClose={handleClose}
TransitionComponent={Transition}
>
<DialogTitle>Confirm</DialogTitle>
<DialogContent>
<DialogContentText>Are you sure?</DialogContentText>
</DialogContent>
<DialogActions>
<Button onClick={handleClose} color="primary">
no
</Button>
<Button onClick={handleClose} color="primary" autoFocus>
yes
</Button>
</DialogActions>
</Dialog>
</div>
);
}
We created the Transition component which uses the Slide component to create a slide down effect.
direction sets the direction of the slide.
We’ve to pass the ref of the dialog into the Slide prop to make it slide.
Then we add the TransitionComponent prop to pass in the Transition component to it.
Form Dialogs
We can add forms inside dialog boxes.
For example, we can write:
import React from "react";
import Button from "@material-ui/core/Button";
import Dialog from "@material-ui/core/Dialog";
import DialogTitle from "@material-ui/core/DialogTitle";
import DialogContent from "@material-ui/core/DialogContent";
import DialogContentText from "@material-ui/core/DialogContentText";
import DialogActions from "@material-ui/core/DialogActions";
import TextField from "@material-ui/core/TextField";
export default function App() {
const [open, setOpen] = React.useState(false);
const handleClose = () => {
setOpen(false);
};
return (
<div>
<Button variant="outlined" color="primary" onClick={() => setOpen(true)}>
Open simple dialog
</Button>
<Dialog open={open} onClose={handleClose}>
<DialogTitle>Confirm</DialogTitle>
<DialogContent>
<DialogContentText>Enter your name</DialogContentText>
<TextField
autoFocus
margin="dense"
id="name"
label="name"
type="text"
fullWidth
/>
</DialogContent>
<DialogActions>
<Button onClick={handleClose} color="primary">
cancel
</Button>
<Button onClick={handleClose} color="primary" autoFocus>
ok
</Button>
</DialogActions>
</Dialog>
</div>
);
}
to add a TextField inside our dialog box.
We make it full width with the fullWidth prop to make it fit inside the dialog box.
Conclusion
We can add a dialog to display various things.
It can include buttons and forms.
Transition effects can also be included.
