Splitter
Resizable panes that preserve the content inside them.
Live TypeScript example
Try the component here, then use the source below in your application.
Drag the divider, or focus it and use the arrow keys. The draft input stays intact.
import '@bluui/web/styles.css'
import { createSplitter } from "@bluui/web";
export function mount(host: HTMLElement) {
const note = document.createElement("input");
note.value = "Draft survives resizing";
note.setAttribute("aria-label", "Draft note");
return createSplitter(
host,
{
PrimaryContent: note,
SecondaryContent: "Drag the divider, or focus it and use the arrow keys.",
PrimarySize: 35,
Height: "300px",
IsCollapsible: true,
},
{
LayoutChanged: (size, collapsed) => {
host.dataset.layout = JSON.stringify({ size, collapsed });
},
},
);
}
const instance = mount(document.getElementById('example')!)
// When this page or framework component is removed:
// instance.destroy()
Install the library and add the host element
npm install https://bluui.blutekmedia.com/downloads/bluui-web-0.2.6.tgz<div id="example"></div>This example uses the downloadable @bluui/web package. Your application handles persistence and authentication through its typed callbacks. The starter ZIP includes this same example.

Evidence and remaining verification →Purpose and use
Use Splitter for a persistent navigation/detail or editor/preview workspace. Choose minimum sizes that keep both panes useful.
Keyboard design guidance
Focus the separator. Arrow keys resize, Shift increases the step, Home and End use the limits, Enter collapses or expands, and Escape cancels a pointer drag.
This describes the intended interaction. The dated audit above identifies verified behavior and current gaps.
In your application
Provide useful labels, preserve visible focus, and test the component with your actual content. Use text alongside status colors and check contrast in each state.
