ajax loaded data parent detection

[pajooh]

in a tree that nodes are loaded asynchronously (e.g. by clicking on parent node),
every node initially is considered as leaf, as it has no children loaded.
as a workaround, it can be another property like is_parent, to indicate parent nodes from leafs.

I am not sure I understand the issue.
The tree should be update as you update the model - reflecting the change in the tree DOM based on the change in the data.

Can you share a gist / fiddle to demonstrate the problem?

[pajooh]

the tree updates as excepted, but the problem is what icon (leaf/expandable) to show
initially, as every top level node has no children, every node is treated as a leaf (with leaf icon). clicking on each node will load it's children and the clicked node icon changes to expandable icon

i 'm talking about making a node with expandable icon even without any children loaded

got it. will have to think how to support such a use case.

implemented a solution isLeaf method in options - which allows you to select if a node is a leaf or a branch. The method accepts a node and returns boolean.
