[Treantjs]: How to make the root node collapsed?

[egor-progger]

Description from treantjs issue

Hi,

I want to make the root node collapsed. Here is what my configuration:

{"chart":{"container":"#ngpTree","animateOnInit":true,"node":{"collapsable":true},"animation":{"nodeAnimation":"easeOutBounce","nodeSpeed":700,"connectorsAnimation":"bounce","connectorsSpeed":700}},"nodeStructure":{"collapsed":true,"innerHTML":"\n

=>=>7 1 2 3 4 \n ","text":{"name":7},"children":[{"collapsed":true,"innerHTML":"\n=>=>3 1 3 \n ","text":{"name":3},"children":[{"collapsed":true,"innerHTML":"\n=>=>0 1 \n ","text":{"name":0},"children":[]}]},{"collapsed":true,"innerHTML":"\n=>=>3 1 2 \n ","text":{"name":3},"children":[{"collapsed":true,"innerHTML":"\n=>=>1 1 \n ","text":{"name":1},"children":[]}]}]}}

You see in nodeStructure of root node, I set collapsed to true as what I did for each child node:

"nodeStructure":{"collapsed":true,"innerHTML":....

However the root node still is not collapsed, the children nodes are collapsed as I wanted.

Is this the way I make the root node collapsed? If not, how?

Thanks,

Stephen
