[EuiResizableContainer] Needs `isCollapsed` option

[KishorBudhathoki10]

It will be nice to have a props like isCollapsed for Resizeable Panel. I have a page where I have a resizable component. But when I go from one page to another the resizeable panel goes back to its previous state. I can manage the size of the panels but not collapsible state.

So there actually should be a way to handle this already since you can trigger the collapsed state from outside of the container. I took the last example and added a useEffect to trigger the onChange even initially setting the id of a collapsed panel to 2. https://codesandbox.io/s/interesting-microservice-tkfu1

I'm not 100% sure this is the correct way, but it seems to work. @thompsongl Might have more info.

The useEffect method will work, but it's reasonable that there should be an isCollapsed and/or initialIsCollapsed prop on EuiResizablePanel.

Edit: I think initialIsCollapsed makes the most sense. The essential use case being to re-enable the previous state on mount.

@cchaos I saw in the examples that using buttons we can manage to hide the panel. But, to keep it collapsed with the open icon it does not seem to work. It seems that the collapsed panel gets the width of 33.33% as a inline style. Maybe cause of flex but not sure. You can check it in this link https://codesandbox.io/s/billowing-night-wsw1p.

In the code from sand box that I linked, if you changed the useEffect to:

 useEffect(() => {
    setTimeout(() => {
      onChange(1);
    }, 0);
  }, []);

It seems to work but with a glitch.

@thompsongl I also think initialIsCollapsed makes lot of sense.

Thanks for reopening! We came up with a use-case when a resizable container with the isCollapsed prop would come in handy because we'd like to preserve it from the localStorage.
