Tree grouping

Webix JS
1

Is it possible to group the tree from the child data?. For example, I would like to group with the format attribute from the child.

Yep, you can use functions instead of the property names for more precise configuration.

Thank you. That was working perfect. If the scenario is like below, is it still possible to group?

Grouping put one item in one group, in your case the same item need to be placed in different branches of the tree, so it can’t be achieved with grouping.

You can use some custom js code which will convert an incoming data to a final JSON structure for the tree.
