sidlayouter

Sidlayouter is a layout management component designed to organize user interfaces into side regions and a central content area. It is commonly used in web applications and desktop UI toolkits to create two- or multi-column layouts with collapsible sidebars and adjustable panes.

Key features typically include support for left and right sidebars, multiple panes, collapsible and resizable panels, and responsive behavior through breakpoints. It often provides options to set minimum and maximum widths, persist layout state across sessions, and ensure accessibility through keyboard controls and ARIA roles. The component is generally designed to be framework-agnostic, working with plain HTML/CSS or inside modern UI frameworks.

Architecture and implementation generally describe Sidlayouter as a modular library that exposes an API to declare regions (such as left, main, right), configure their sizes, and render the layout when mounted. It relies on standard CSS layout techniques like flexbox or CSS grid and offers JavaScript hooks to respond to resize events, toggle visibility, and save or restore layout state. While it can be used directly in vanilla JavaScript, it is commonly wrapped as components for frameworks such as React, Vue, or Svelte.

Usage typically involves defining the regions, setting width constraints and behavior (collapsible, resizable), mounting the layout to a DOM element, and optionally enabling state persistence or keyboard shortcuts. A minimal example includes creating a Sidlayouter instance with region definitions and mounting it to a container element, then adjusting options as needed.
