lockItem is not working


I’m trying to use the lockItem function in my js, and couldn’t make it work. So I tried the exmaple on your website: dhtmlx.com/docs/products/dht … _tree.html

It’s not working either. For exmaple, I locked the node “Dan Brown”. Even though the icon changed for this node, I could still expand/collapse the node. Please advice. Thank you!

Have you included dhtmlxtree_li.js extention in the library? It is PRO possibility.

Yes, I included the required js file. Also, I assume the sample page must have included the js file? It’s not working even there…
