React Side Panels that Collapse and Expand

Question

React Side Panels that Collapse and Expand

Apologies if this task seems simple, as I am new to transitioning to React. My current application is primarily built with JavaScript, CSS, and HTML, and I am now looking to migrate it to React. There is a full-length horizontal side panel that is initially open, collapses into a hamburger icon when the window shrinks, and expands again when resized larger - all achievable with media queries in CSS.

A good reference for what I am trying to achieve can be found at (take note of the side menu). It aligns closely with the functionality of my current app.

My struggle lies in implementing this design in React. While I can create a collapsible side panel using a component like in and customize it, I am unable to set it up for automatic collapse and expansion. Although I know I can utilize media queries in React, I believe there might be a more efficient approach.

I would greatly appreciate any recommendations for libraries or examples that could help me accomplish this task.

Here is an example of how you can implement this functionality:

const CustomComponent = props => {
  const [viewportWidth, setViewportWidth] = useState(0)

  useEffect(() => {
    window.addEventListener('resize', updateViewportDimensions)
    updateViewportDimensions()
    return () => window.removeEventListener('resize', updateViewportDimensions)
  }, [])

  useEffect(() => {
    if (viewportWidth < 500) {
      closeOverlay()
      return
    }
    openOverlay()
  }, [viewportWidth])

  function updateViewportDimensions() {
    setViewportWidth(window.innerWidth)
  }
}
