Hi
You can use userdata property:
dhtmlx.com/docs/products/dhtmlxT … _data.html
docs.dhtmlx.com/api__dhtmlxtree_setuserdata.html

it’s very trouble by use “user data”…
it’s no any methods on it…?
if not,i have to change another tree which support it.
i think plus this function is easy to dhtmlx…i don’t know why not.
loading data efficiency,i don’t think so…

You can use custom attribute. Like below:

<item text="Dan Brown" open="1" id="db" type="bbb">

There is a “type” attribute
