I have a problem, I need a scrollable tree with multiple columns that has dynamic height. I've found two solutions, but none of them is perfect. 1) defining number of rows in tree element. That works OK - header is static and content is scrolled, but this is not dynamic tree. 2) stetting style="overflow-y:auto" on tree element that but that scrolls whole tree (including header) and she scrollbar is placed over the header - so the label is partially unreadable.

Something tells me that some smart JS can calculate the rows attribute (but I wonder if there is some better way to do it). I'd like to upload some screen shots of the example but my Karma is to low.

Thanks for any ideas.

Hey Jovkub,

I altered a little bit your sample :

http://zkfiddle.org/sample/2gsu84m/2-Table-scrolling-example

Look at the right one.

Now, looks like I discovered a small GUI issue of ZK. height="100% seems it counts for z-tree-body but he don't calculate the z-tree-header height with it.
That's why I needed it to fix with setting the same height as the parent object.

With MVVM you can make this dynamic => height="@load(vm.treeHeight)" (in div and tree)
Then in the VM you just have a getter :

public String getTreeHeight() {
   return treeHeight; // where treeHeight = "135px"
}

Hope this can help you further.
If any more questions, just ask.

Greetz Chill.

After some playing with trees I've found that vflex instead height shall be used on tree element. Now it works like charm.

lol, I was assuming that you had to set your height manually(depending on some configs). Vflex works as a charm indeed.
