# Split Panel
|
|
|
|
[component-header:sl-split-panel]
|
|
|
|
Split panels display two adjacent panels, allowing the user to reposition them.
|
|
|
|
```html preview
|
|
<sl-split-panel>
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlSplitPanel } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => (
|
|
<SlSplitPanel>
|
|
<div
|
|
slot="start"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
End
|
|
</div>
|
|
</SlSplitPanel>
|
|
);
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Initial Position
|
|
|
|
To set the initial position, use the `position` attribute. If no position is provided, it will default to 50% of the available space.
|
|
|
|
```html preview
|
|
<sl-split-panel position="75">
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
### Initial Position in Pixels
|
|
|
|
To set the initial position in pixels instead of a percentage, use the `position-in-pixels` attribute.
|
|
|
|
```html preview
|
|
<sl-split-panel position-in-pixels="150">
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlSplitPanel } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => (
|
|
<SlSplitPanel position="200">
|
|
<div
|
|
slot="start"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
End
|
|
</div>
|
|
</SlSplitPanel>
|
|
);
|
|
```
|
|
|
|
### Vertical
|
|
|
|
Add the `vertical` attribute to render the split panel in a vertical orientation where the start and end panels are stacked. You also need to set a height when using the vertical orientation.
|
|
|
|
```html preview
|
|
<sl-split-panel vertical style="height: 400px;">
|
|
<div
|
|
slot="start"
|
|
style="height: 100%; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 100%; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlSplitPanel } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => (
|
|
<SlSplitPanel vertical style={{ height: '400px' }}>
|
|
<div
|
|
slot="start"
|
|
style={{
|
|
height: '100%',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style={{
|
|
height: '100%',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
End
|
|
</div>
|
|
</SlSplitPanel>
|
|
);
|
|
```
|
|
|
|
### Snapping
|
|
|
|
To snap panels at specific positions while dragging, add the `snap` attribute with one or more space-separated values. Values must be in pixels or percentages. For example, to snap the panel at `100px` and `50%`, use `snap="100px 50%"`. You can also customize how close the divider must be before snapping with the `snap-threshold` attribute.
|
|
|
|
```html preview
|
|
<div class="split-panel-snapping">
|
|
<sl-split-panel snap="100px 50%">
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
|

|

.split-panel-snapping-dots::after {

}
|

</style>
|

```
|
|

### Disabled
|
|
|
|
Add the `disabled` attribute to prevent the divider from being repositioned.
|
|
|
|
```html preview
|
|
<sl-split-panel disabled>
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlSplitPanel } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => (
|
|
<SlSplitPanel disabled>
|
|
<div
|
|
slot="start"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
End
|
|
</div>
|
|
</SlSplitPanel>
|
|
);
|
|
```
|
|
|
|
### Setting the Primary Panel
|
|
|
|
By default, both panels will grow or shrink proportionally when the host element is resized. If a primary panel is designated, it will maintain its size and the secondary panel will grow or shrink to fit the remaining space. You can set the primary panel to `start` or `end` using the `primary` attribute.
|
|
|
|
Try resizing the example below with each option and notice how the panels respond.
|
|
|
|
```html preview
|
|
<div class="split-panel-primary">
|
|
<sl-split-panel>
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
|
|
<sl-select label="Primary Panel" value="" style="max-width: 200px; margin-top: 1rem;">
|
|
<sl-menu-item value="">None</sl-menu-item>
|
|
<sl-menu-item value="start">Start</sl-menu-item>
|
|
<sl-menu-item value="end">End</sl-menu-item>
|
|
</sl-select>
|
|
</div>
|
|
|
|
<script>
|
|
const container = document.querySelector('.split-panel-primary');
|
|
const splitPanel = container.querySelector('sl-split-panel');
|
|
const select = container.querySelector('sl-select');
|
|
|
|
select.addEventListener('sl-change', () => (splitPanel.primary = select.value));
|
|
</script>
|
|
```
|
|
|
|
```jsx react
|
|
import { useState } from 'react';
|
|
import { SlSplitPanel, SlSelect, SlMenuItem } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => {
|
|
const [primary, setPrimary] = useState('');
|
|
|
|
return (
|
|
<>
|
|
<SlSplitPanel primary={primary}>
|
|
<div
|
|
slot="start"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
End
|
|
</div>
|
|
</SlSplitPanel>
|
|
|
|
<SlSelect
|
|
label="Primary Panel"
|
|
value={primary}
|
|
style={{ maxWidth: '200px', marginTop: '1rem' }}
|
|
onSlChange={event => setPrimary(event.target.value)}
|
|
>
|
|
<SlMenuItem value="">None</SlMenuItem>
|
|
<SlMenuItem value="start">Start</SlMenuItem>
|
|
<SlMenuItem value="end">End</SlMenuItem>
|
|
</SlSelect>
|
|
</>
|
|
);
|
|
};
|
|
```
|
|
|
|
### Min & Max
|
|
|
|
To set a minimum or maximum size of the primary panel, use the `--min` and `--max` custom properties. Since the secondary panel is flexible, size constraints can only be applied to the primary panel. If no primary panel is designated, these constraints will be applied to the `start` panel.
|
|
|
|
This examples demonstrates how you can ensure both panels are at least 150px using `--min`, `--max`, and the `calc()` function.
|
|
|
|
```html preview
|
|
<sl-split-panel style="--min: 150px; --max: calc(100% - 150px);">
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlSplitPanel } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => (
|
|
<SlSplitPanel style={{ '--min': '150px', '--max': 'calc(100% - 150px)' }}>
|
|
<div
|
|
slot="start"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
End
|
|
</div>
|
|
</SlSplitPanel>
|
|
);
|
|
```
|
|
|
|
### Nested Split Panels
|
|
|
|
Create complex layouts that can be repositioned independently by nesting split panels.
|
|
|
|
```html preview
|
|
<sl-split-panel>
|
|
<div
|
|
slot="start"
|
|
style="height: 400px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div slot="end">
|
|
<sl-split-panel vertical style="height: 400px;">
|
|
<div
|
|
slot="start"
|
|
style="height: 100%; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Top
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 100%; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|

|
|
Bottom
|
|
</div>
|
|
</sl-split-panel>
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlSplitPanel } from '@shoelace-style/shoelace/dist/react';
|

|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div slot="end">
|
|

### Customizing the Divider

|
|
|
You can target the `divider` part to apply CSS properties to the divider. To add a handle, slot an icon or another element into the `handle` slot. When customizing the divider, make sure to think about focus styles for keyboard users.

|
```html preview
|
|
<sl-split-panel style="--divider-width: 20px;">
|
|
<sl-icon slot="handle" name="grip-vertical"></sl-icon>
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlSplitPanel, SlIcon } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => (
|
|
<SlSplitPanel style={{ '--divider-width': '20px' }}>
|
|
<SlIcon slot="handle" name="grip-vertical" />
|
|
<div
|
|
slot="start"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style={{
|
|
height: '200px',
|
|
background: 'var(--sl-color-neutral-50)',
|
|
display: 'flex',
|
|
alignItems: 'center',
|
|
justifyContent: 'center'
|
|
}}
|
|
>
|
|
End
|
|
</div>
|
|
</SlSplitPanel>
|
|
);
|
|
```
|
|
|
|
Here's a more elaborate example that changes the divider's color and width and adds a styled handle.
|
|
|
|
```html preview
|
|
<div class="split-panel-handle">
|
|
<sl-split-panel>
|
|
<sl-icon slot="handle" name="grip-vertical"></sl-icon>
|
|
<div
|
|
slot="start"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
Start
|
|
</div>
|
|
<div
|
|
slot="end"
|
|
style="height: 200px; background: var(--sl-color-neutral-50); display: flex; align-items: center; justify-content: center;"
|
|
>
|
|
End
|
|
</div>
|
|
</sl-split-panel>
|
|
</div>
|
|
|
|
<style>
|
|
.split-panel-handle sl-split-panel {
|
|
--divider-width: 2px;
|
|
}
|
|
|
|
.split-panel-handle sl-split-panel::part(divider) {
|
|
background-color: var(--sl-color-pink-600);
|
|
}
|
|
|
|
.split-panel-handle sl-icon {
|
|
position: absolute;
|
|
border-radius: var(--sl-border-radius-small);
|
|

|
|

|
|

|
|
}
|
|
|
|
.split-panel-handle sl-split-panel::part(divider):focus-visible {
|
|
background-color: var(--sl-color-primary-600);
|
|
}
|
|
|
|
.split-panel-handle sl-split-panel:focus-within sl-icon {
|
|
background-color: var(--sl-color-primary-600);
|
