Feature Suggestion - Virtual Scrolling for speed & 1 million nodes

[jplevene]

IGNORE & DELETE THIS AS I SAW THIS WILL BE HAPPENING IN VERSION 4

Saw another plugin that did this, and was really impressed. It's sort of a bit like REACT

Basically, only nodes that are visible would be rendered in the DOM, everything above and below the visible pane is just a single div element, set to the out of view nodes height.

This would enable jsTree to have 1 million open nodes and work really fast, just like there were 20.

This is a demo of a table plugin that does this: https://paramquery.com/pro/demos/infiniteV.

Above are 1 million rows and it renders and scrolls like there are 6, because in essence, there are only 6 rows + the space above and below in the DOM.

I haven't looked too hard into the example, but it seems to remove a row from the DOM when it goes out view and create one at the other end in the DOM when it comes into view.

I just came by to tell you to check out v4 - it already has this functionality.

Thanks. Does V4 have the plugins working yet? I can see that it hasn't been touched for 8 months.
