I found some samples on the site that give clues to how to form proper JSON to load the TreeGrid the way I want… and I have succeeded in getting information to load … but there is nothing documentation-wise to show me all the options I have in JSON for loading the tree grid.
I found a page for the DHTMLTree
docs.dhtmlx.com/tree__syntax_tem … attemplate
But not the TreeGrid. I tried to use an “open” property I saw documented for DHTMLXTree, but nothing happened.
Specifically right now I am looking for information that I can put in my JSON value to specify which tree nodes start out as expanded.
Let me know. Thanks!
