Female and male placeholder when using the library on react

[matthewfelixr]

Good day Mr. SanichKotikov,

First of all, thank you for making this library, im very happy to know that there are usable library like this with 2 parents.. but i encountered some Issue that Even i only had 1 Node, it popped up a parent Node , female-placeholder and male-placeholder.. i would like to know how to hide those placeholder if i wanted the top node does not have any parents?

and secondly, i wanna know how pinch-zoom-pan works at current version.. since i want to know how to implement the zoom and draggable motion only in one div tags, and when i try it, my whole page can be dragged

I hope you're gonna respond to this, thanks in advance Mr. Sanich Kotikov

Hi, thanks!

1. You have to call calculation without placeholders option or set it to false, for example lake this calcTree(nodes, { rootId }).
2. You can check source here https://github.com/SanichKotikov/pinch-zoom-pan
