Hi, I tried to pass in option: `toggleSiblingsResp` but it doesn't seem to be working. ```js orgchart = new OrgChart({ 'chartContainer': '#chart-container', 'data' : datascource, nodeContent: 'title', toggleSiblingsResp: false }); ``` Another question is how can I disable toggle parent ? I want to limit ability to hide parent of a child node.
