Well done!
Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.
Whenever you need to, be sure to use margin utilities to keep things nice and tidy.

import { MDBAlert } from 'mdb-react-ui-kit';
export default function App() {
return (

}
Show with trigger
You can manually show alert using triggerRef property with other element.
Hidden alert!
import React, { useRef } from 'react';
import { MDBAlert, MDBContainer, MDBBtn } from 'mdb-react-ui-kit';
export default function App() {
const triggerRef = useRef(null);
return (
<MDBContainer className='text-center'>
<MDBBtn ref={triggerRef}>Show alert!</MDBBtn>
<MDBAlert triggerRef={triggerRef} className='mt-3 w-100' color='primary'>
Hidden alert!
</MDBAlert>
</MDBContainer>
);
}
Hide
You can manually hide alert using show prop.
Hide me!
import React, { useState } from 'react';
import { MDBAlert, MDBContainer, MDBBtn } from 'mdb-react-ui-kit';
export default function App() {
const [visibility, setVisibility] = useState(true);
return (
<MDBContainer className='text-center'>
<MDBBtn onClick={() => setVisibility(false)}>Hide me!</MDBBtn>
<MDBAlert show={visibility} className='mt-3 w-100' color='primary'>
Hide me!
</MDBAlert>
</MDBContainer>
);
}
Placement
You can set the position of every alert using the
position property.
Select horizontal / vertical alignment
Current position: top-right
Show me wherever you want!
import React, { useRef } from 'react';
import { MDBAlert, MDBContainer, MDBBtn } from 'mdb-react-ui-kit';
export default function App() {
const placementExample = useRef(null);
return (
<MDBContainer className='text-center'>
<MDBBtn ref={placementExample}>Show!</MDBBtn>
<MDBAlert
color='primary'
autohide
position='top-right'
delay={2000}
appendToBody
triggerRef={placementExample}
>
Show me wherever you want!
</MDBAlert>
</MDBContainer>
);
}
Container
You can display an alert anywhere. Just put it in your target element and fill the
containerRef property with reference to the parent.
Hello from parent element!
import React, { useRef } from 'react';
import { MDBAlert, MDBBtn } from 'mdb-react-ui-kit';
export default function App() {
const triggerContainer = useRef(null);
const wrapperRef = useRef(null);
return (
<div className='container text-center' ref={wrapperRef}>
<MDBBtn className='mb-5' ref={triggerContainer}>
Show alert below!
</MDBBtn>
<MDBAlert
color='primary'
autohide
position='top-right'
delay={3000}
triggerRef={triggerContainer}
containerRef={wrapperRef}
>
Hello from parent element!
</MDBAlert>
</div>
);
}
Offset
You can set offset of your alert using a offset property.
Offset: 100px
import React, { useRef } from 'react';
import { MDBAlert, MDBBtn } from 'mdb-react-ui-kit';
export default function App() {
const triggerOffset = useRef(null);
return (
<>
<MDBBtn className='mb-5' ref={triggerOffset}>
Show alert with offset!
</MDBBtn>
<MDBAlert
color='primary'
autohide
offset={100}
position='top-right'
delay={3000}
triggerRef={triggerOffset}
>
Offset: 100px
</MDBAlert>
</>
);
}
Stacking
You can turn on stacking your alerts using the
stacking property.
import React, { useState } from 'react';
import { MDBAlert, MDBBtn } from 'mdb-react-ui-kit';
export default function App() {
const [stackingAlerts, setStackingAlerts] = useState<{}[]>([]);
const [stackingColor, setStackingColor] = useState(0);
const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];
const handleStackingClick = () => {
stackingColor + 1 > colors.length - 1 ? setStackingColor(0) : setStackingColor(stackingColor + 1);
const ID = Math.random().toString();
setStackingAlerts([
...stackingAlerts,
{
color: colors[stackingColor],
count: stackingAlerts.length > 0 ? stackingAlerts.length + 1 : 1,
visible: true,
id: ID,
},
]);
};
const handleCloseStackingClick = (number) => {
const tempStackingAlerts = [];
stackingAlerts.forEach((alert) => {
if (alert.id === number) {
tempStackingAlerts.push({
color: alert.color,
count: alert.count,
visible: false,
id: alert.id,
});
return;
}
tempStackingAlerts.push(alert);
});
setStackingAlerts(tempStackingAlerts);
};
return (
<>
<MDBBtn className='m-1' onClick={handleStackingClick}>
Show notification
</MDBBtn>
{stackingAlerts.map((item) => {
return (
<MDBAlert
className='d-flex justify-content-between'
color={item.color}
stacking
autohide
width={450}
position='bottom-right'
offset={10}
delay={8000}
appendToBody
show={item.visible}
key={item.id}
>
<p className='mb-0'>
<strong>{item.count}.</strong> Stacking alerts
</p>
<MDBBtn
className='btn-close'
noRipple
outline
color='none'
onClick={() => handleCloseStackingClick(item.id)}
/>
</MDBAlert>
))}
</>
);
}
Stacking - Container
You can also stack alerts inside the container
import React, { useState, useRef } from 'react';
import { MDBAlert, MDBBtn } from 'mdb-react-ui-kit';
export default function App() {
const [stackingAlertsContainer, setStackingAlertsContainer] = useState<{}[]>([]);
const [stackingColorContainer, setStackingColorContainer] = useState(0);
const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];
const stackingContainer = useRef(null);
const handleStackingClickContainer = () => {
stackingColorContainer + 1 > colors.length - 1
? setStackingColorContainer(0)
: setStackingColorContainer(stackingColorContainer + 1);
const ID = Math.random().toString();
setStackingAlertsContainer([
...stackingAlertsContainer,
{
color: colors[stackingColorContainer],
count: stackingAlertsContainer.length > 0 ? stackingAlertsContainer.length + 1 : 1,
visible: true,
id: ID,
},
]);
};
const handleCloseStackingContainerClick = (number) => {
const tempStackingContainerAlerts = [];
stackingAlertsContainer.forEach((alert) => {
if (alert.id === number) {
tempStackingContainerAlerts.push({
color: alert.color,
count: alert.count,
visible: false,
id: alert.id,
});
return;
}
tempStackingContainerAlerts.push(alert);
});
setStackingAlertsContainer(tempStackingContainerAlerts);
};
return (
<div className='container text-center' ref={stackingContainer}>
<MDBBtn className='m-1' onClick={handleStackingClickContainer}>
Show notification
</MDBBtn>
{stackingAlertsContainer.map((item) => (
<MDBAlert

autohide
width={250}
position='top-right'
delay={2000}
