svelte-split-pane

A <SplitPane> component.

Usage

<script>
  import { SplitPane } from '@rich_harris/svelte-split-pane';

  const dividerColor = 'black';
  const dividerThickness = '20px';
</script>

<SplitPane
  type="horizontal"
  id="main"
  min="100px"
  max="-100px"
  pos="50%"
  priority="min"
  --color={dividerColor}
  --thickness={dividerThickness}
>
  <section slot="a">this is on the left</section>
  <section slot="b">this is on the right</section>
</SplitPane>

Of the properties that can be set on the component, only type is required:

• type can be horizontal, in which case the panes will be split left-right, or vertical in which case it will be split top-bottom
• id will be added to the element as a data-pane={id} attribute, allowing you to (for example) override the --pos CSS custom property on mobile
• min, max and pos can be expressed as ${number}%, ${number}px, ${number}em or ${number}rem. Positive numbers are measured from the left/top, negative numbers are measured from the right/bottom
• priority determines whether the min or max constraint wins in cases where they conflict
• --color determines the color of the divider between panes, and defaults to transparent
• --thickness determines how thick the 'hit area' is for the divider, and defaults to 8px
