Resizable Drawer with Mouse Drag

Steps

Create resize handle with styled-components:

const ResizableHandle = styled.div`
  position: absolute; left: 0; top: 0; bottom: 0;
  width: 4px; cursor: col-resize; z-index: 10;
  &:hover { background: var(--color-border-interactive); }
`;

Add mouse event listeners for drag:

const onMouseDown = (e) => {
  e.preventDefault();
  const startX = e.clientX;
  const startWidth = currentWidth;

  // Suppress transition during drag
  const wrapper = document.querySelector('.ant-drawer-content-wrapper');
  if (wrapper) wrapper.style.transition = 'none';

  const onMouseMove = (moveE) => {
    const newWidth = Math.min(MAX_WIDTH, Math.max(MIN_WIDTH, startWidth + (startX - moveE.clientX)));
    setWidth(newWidth);
  };

  const onMouseUp = () => {
    if (wrapper) wrapper.style.transition = '';
    document.removeEventListener('mousemove', onMouseMove);
    document.removeEventListener('mouseup', onMouseUp);
  };

  document.addEventListener('mousemove', onMouseMove);
  document.addEventListener('mouseup', onMouseUp);
};

Define constraints:
- MIN_WIDTH = 440 (minimum usable content width)
- MAX_WIDTH = window.innerWidth - menuOffset (don't overlap sidebar)

Apply width to Ant Drawer:

<Drawer width={width} {...props}>
  <ResizableHandle onMouseDown={onMouseDown} />
  {children}
</Drawer>

Key details

Setting transition: 'none' on .ant-drawer-content-wrapper during drag prevents jittery animation
Restore transition on mouseup for smooth open/close animation
menuOffset accounts for sidebar width in the host layout
