Additional Content
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 React from 'react';
import { MDBAlert } from 'mdb-react-ui-kit';
export default function App() {
return (
<MDBAlert show className='w-100' color='success'>
<h4 className='alert-heading'>Well done!</h4>

);
}
Show with trigger
You can manually show alert using triggerRef
property with other element.
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>
);
}
Placement
You can set the position of every alert using the
position
property.
Select horizontal / vertical alignment
Current position: top-right
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.
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.
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<Array<Record<string, any>>>([]);
const [stackingColor, setStackingColor] = useState(0);
const handleClick = () => {
const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];
stackingColor + 1 > colors.length - 1 ? setStackingColor(0) : setStackingColor(stackingColor + 1);
setStackingAlerts([
...stackingAlerts,
{
color: colors[stackingColor],
count: stackingAlerts.length > 0 ? stackingAlerts.length + 1 : 1,
},
]);
};
return (
<>
<MDBBtn className='m-1' onClick={handleClick}>
Show notification
</MDBBtn>
{stackingAlerts.map((item) => (
<MDBAlert
color={item.color}
stacking
autohide
width={450}
position='bottom-right'
offset={50}
delay={2000}
appendToBody
show
key={item.count}
>
<p className='mb-0'>
<strong>{item.count}.</strong> Stacking alerts
</p>
</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 [containerAlerts, setContainerAlerts] = useState<Array<Record<string, any>>>([]);
const [containerColor, setContainerColor] = useState(0);
const handleContainerClick = () => {
const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];
containerColor + 1 > colors.length - 1 ? setContainerColor(0) : setContainerColor(containerColor + 1);
setContainerAlerts([
...containerAlerts,
{
color: colors[containerColor],
count: containerAlerts.length > 0 ? containerAlerts.length + 1 : 1,
},
]);
};
const stackingContainer = useRef(null);
return (
<div className='container text-center' ref={stackingContainer}>
<MDBBtn className='m-1' onClick={handleContainerClick}>
Show notification
</MDBBtn>
{containerAlerts.map((item) => (
<MDBAlert
color={item.color}
stacking
offset={30}
autohide
width={250}
position='top-right'
delay={2000}
show
containerRef={stackingContainer}
key={item.count}
>
<p className='mb-0'>
<strong>{item.count}.</strong> Stacking alerts
</p>
</MDBAlert>
))}
</div>
);
