[component-header:sl-progress-bar]
<sl-progress-bar value="50"></sl-progress-bar>
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
const App = () => <SlProgressBar value={50} />;
Examples
Labels
Use the label
attribute to label the progress bar and tell assistive devices how to announce it.
<sl-progress-bar value="50" label="Upload progress"></sl-progress-bar>
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
const App = () => <SlProgressBar value="50" label="Upload progress" />;
Custom Height
Use the --height
custom property to set the progress bar's height.
<sl-progress-bar value="50" style="--height: 6px;"></sl-progress-bar>
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
const App = () => <SlProgressBar value={50} style={{ '--height': '6px' }} />;
Showing Values
Use the default slot to show a value.
<sl-progress-bar value="50" class="progress-bar-values">50%</sl-progress-bar>
<br />
<sl-button circle><sl-icon name="dash" label="Decrease"></sl-icon></sl-button>
<sl-button circle><sl-icon name="plus" label="Increase"></sl-icon></sl-button>
<script>
const progressBar = document.querySelector('.progress-bar-values');
const subtractButton = progressBar.nextElementSibling.nextElementSibling;
const addButton = subtractButton.nextElementSibling;
addButton.addEventListener('click', () => {
const value = Math.min(100, progressBar.value + 10);
progressBar.value = value;
progressBar.textContent = `${value}%`;
});
subtractButton.addEventListener('click', () => {
const value = Math.max(0, progressBar.value - 10);
progressBar.value = value;
progressBar.textContent = `${value}%`;
});
</script>
import { useState } from 'react';
import { SlButton, SlIcon, SlProgressBar } from '@shoelace-style/shoelace/dist/react';
const App = () => {
const [value, setValue] = useState(50);
function adjustValue(amount) {
let newValue = value + amount;
if (newValue < 0) newValue = 0;
if (newValue > 100) newValue = 100;
setValue(newValue);
}
return (
<>
<SlProgressBar value={value}>{value}%</SlProgressBar>
<br />
<SlButton circle onClick={() => adjustValue(-10)}>
<SlIcon name="dash" label="Decrease" />
</SlButton>
<SlButton circle onClick={() => adjustValue(10)}>
<SlIcon name="plus" label="Increase" />
</SlButton>
</>
);
};
Indeterminate
The indeterminate
attribute can be used to inform the user that the operation is pending, but its status cannot currently be determined. In this state, value
is ignored and the label, if present, will not be shown.
<sl-progress-bar indeterminate></sl-progress-bar>
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
const App = () => <SlProgressBar indeterminate />;
