How to expand all ancestor nodes by a child node (selected or actived) automatically?

[huna...@gmail.com]

I got tree data like this :

var treeData = [
{
title : "Root Node", folder : true, key : "id1",
children : [
{ title : "Sub-item 1.1", key : "id1.1" },
{
title : "Sub-item 1.2", folder : true, key: "id1.2",
children : [
{ title : "Sub-item 1.2.1", key : "id1.2.1" },
{ title : "Sub-item 1.2.2", key : "id1.2.2" },
{
title : "Sub-item 1.3.1", folder : true, key : "id1.3.1",
children : [
{ title : "Sub-item 1.3.1", key : "id1.3.1" },
{ title : "Sub-item 1.3.2", key : "id1.3.2", active : true, selected: true },
{ title : "Sub-item 1.3.3", key : "id1.3.3" }
]
}
]
}
]
}
];

The forth level "Sub-item 1.3.2" has attribute 'avtive' and 'selected',

is there any way to expand it's ancestor node by giving a parameter to the $.fn.fancytree({ ... }) method, or just find ancestor node and set the 'expanded' attribute to 'true'?

Hi there

although your post is old I want to give you a workaround.

This script expands all parents to a n active subnode. The developer of FancyTree opened an issue at GitHub to get the built in solution to work. Until then you can use my solution:

init: function(event, data) {

var activeJumpNode = data.tree.getActiveNode();

if ( activeJumpNode ) {

var treeObj = $("YourSelector").fancytree("getTree");

var jumpToNode = treeObj.findFirst(function(node) {

return node === activeJumpNode;

});

jumpToNode.setActive();

jumpToNode.setFocus();

$(treeObj.$container).focus();

}

}

Does this was finally solved? I'm implementing my own solution, but perhaps there is something built in.
