Material UI grid with independent scrolling columns

问题

I'm looking to make multiple scrolling columns using Material UI in React. I had a way of doing it in bootstrap with flex, but I can't get it to translate over. I have put together a demo of a hacky way to do it that requires knowing the size of the contents above what you're trying to scroll (in this case, the AppBar)

https://codesandbox.io/s/pmly895mm

html,
body {
  margin: 0;
  height: 100%;
}

#root {
  height: 100%;
}

.grid-container {
  height: calc(100% - 64px);
}

.grid-column {
  height: 100%;
  overflow-y: auto;
}

In this demo, I set all of the heights to 100% (html, body, #root) and then created two classes grid-container with a height of 100% - AppBar height and grid-column with a height of 100% and an overflow-y of auto.

In Bootstrap, I would apply these classes to the row and column elements respectively

.flex-section {
  flex-grow: 1;

  display: flex;
  flex-direction: column;

  min-height: 0;
}

.flex-col-scroll {
  flex-grow: 1;

  overflow: auto;

  min-height: 100%;
}

And it wouldn't matter what was above the elements because flex took care of the heights.

Specifically, I am looking to avoid having to do height: calc(100% - 64px) as this requires me knowing the element heights beforehand. I'm going to have some pages where I'd like to put some content above the scrolling area that will have dynamically tall content.

In my determination to recreate how I used to do it in bootstrap (https://jsfiddle.net/aq9Laaew/226591/) I was actually able to get it working in Material UI as well. And since I wasn't able to find any sort of examples of this online for this specific use case (React / Material UI scrollable columns), hopefully this will help someone else.

Here is the example: https://codesandbox.io/s/z24wl3n58m

html,
body {
  margin: 0;
  height: 100%;
}

#root {
  height: 100%;
  display: flex;
  flex-direction: column;
}

.flex-section {
  flex-grow: 1;
  display: flex;
  flex-direction: column;
  min-height: 0;
}

.flex-col-scroll {
  flex-grow: 1;
  overflow: auto;
  min-height: 100%;
}

.flex-no-shrink {
  flex-shrink: 0;
}

What I was missing was setting the flex on the root. Once we do that, then we can utilize flex-section, flex-col-scroll, and flex-no-shrink (the latter of which is used to prevent elements above the scrolling from being compressed)

You just need to make your navbar fixed. It will remain intact to the top. After that, add a padding to you grid container which is going to have all your content. You can even give percentage padding to make sure responsiveness.

Here is the working codesandbox: Fixed Navbar

Let me know if the issue still persists.
