Title: tree: 'closed' elements but loaded
Post by: mzeddd on October 16, 2013, 07:19:34 AM

Hi,

When I use tree or combotree with remote data source.

Looks good but. In case if I load complete tree but have some 'closed' elements then EasyUI works not completely correct.
Even if content is loaded into my branch but branch state is set to 'closed' it tries to load content once again.
As the result I have duplicated elements or complete tree loaded again but into this branch.

Is it possible not to reload branch content if it was loaded but branch was set to 'closed'?

Thanks!

Please refer to this example http://www.jeasyui.com/demo/main/index.php?plugin=Tree&theme=default&dir=ltr&pitem=Async%20Tree.

I mean I have the following tree when everything is open.

Code:

node 1 (open)
   node 1.1
   node 1.2
   node 1.3
node 2 (open)
   node 2.1
   node 2.2
   node 2.3

But I would like to load only part of this tree and keep some elements closed

Code:

node 1 (closed) <- content is loaded already. Just show it when I click on it
   node 1.1
   node 1.2
   node 1.3
node 2 (closed) <- needs to be loaded when I click on it

So for user it will look like

Code:

node 1 (closed)
node 2 (closed)

Please refer to the lazy loading example http://www.jeasyui.com/demo/main/index.php?plugin=Tree&theme=default&dir=ltr&pitem=Lazy%20Load%20Tree%20Nodes.

Thanks for this example.

But don't you think that it would be good idea to have this functionality available by default and don't define extra functions all the time?

Also, would be good to extand this feature request with the following idea:
For example we have a tree like I showed above where "node 2" is closed and not loaded. When I click on it changes its picture from "closed folder" to "open folder".
But in case if you "open" it but don't load any data it does not look great for some cases and would be good to change the picture from "open folder" to "file".
And of course change it from "file" to "open folder" when you add any children into it.
