Looking at the TC docs, Angular JS Trees are not supported directly.
But I had a look at an example one. The one on here: https://angular-ui-tree.github.io/angular-ui-tree/#/basic-example
... and I was able to interact with it easily enough. The tree itself shows as a top level control. All it's nodes show as child items. All text within the nodes was visible and I was able to search by it. And the clickable controls (expand, add, remove) within each node were all accessible and usable. I'd be happy I could build my own handler function to allow me to use them without too much trouble.
Of course, this is based on an example one I happened to find online. I have no idea if the one you're dealing with behaves the same way.
Same goes for this example one: http://www.jqueryrain.com/?KIVkhqxl
It was all there. Think they implemented it slightly differently as it was a little more awkward to interact with. But again, if I took the time, I could build my own handler for it.
Not all controls are supported and do everything you want out of the box. Sometimes you need to build your own solutions I'm afraid. This appears to be one of them. But, going by the examples I can find, it appears to give you all the properties and methods you should need to do exactly that.
