Expand/Collapse

You can specify expand/collapse state by setting expand/collapse options or using tags.

1. Expand and Collapse options

Here is an example how to collpase the chart to the second level:

        var chart = new OrgChart(document.getElementById("tree"), { 
            collapse: {
                level: 2
            },
            ...
        });
    

In the example above if you click the expand button of node with id "2" all children will be expanded.


Here is an example how to collpase the chart to the second level and all children of the second level:

        var chart = new OrgChart(document.getElementById("tree"), { 
            collapse: {
                level: 2,
                allChildren: true
            },
            ...
        });
    

In the example above if you click the expand button of node with id "2" only the children from the third level will be expanded.


Here is an example how to collpase the chart to the second level and all children of the second level, except node with id "4":

        var chart = new OrgChart(document.getElementById("tree"), { 
            collapse: {
                level: 2,
                allChildren: true
            },
            expand: {
                nodes: [4]
            }
            ...
        });
    

Here is an example how to collpase the chart to the second level and all children of the second level, except node with id "4" and its children:

        var chart = new OrgChart(document.getElementById("tree"), { 
            collapse: {
                level: 2,
                allChildren: true
            },
            expand: {
                nodes: [4],
                allChildren: true
            }
            ...
        });
    

2. Expand/Collpase on node click event

To expand or collapse on node click set nodeMouseClick to OrgChart.action.expandCollapse. Here is an example

 
    var chart = new OrgChart(document.getElementById("tree"), {
        nodeMouseClick: OrgChart.action.expandCollapse,
        ...
    });    

In some cases you might not need the expand/collapse button, to hide it you will need to override the template. In the demo bellow all nodes are collapsed:

 
    OrgChart.templates.ana.plus = "";        
    OrgChart.templates.ana.minus = "";
    var chart = new OrgChart(document.getElementById("tree"), {
        template: "ana",
        ...
    });    
    

3. onExpCollClick event

To define custom expand/collpase logic use onExpCollClick event. Here is a demo that you can use to get started.

4. Number of collapsed nodes

To display the number of collapsed nodes change the template as follows:

 
    OrgChart.templates.olivia.plus = '<circle cx="15" cy="15" r="15" fill="#ffffff" stroke="#aeaeae" stroke-width="1"></circle>'
        + '<text text-anchor="middle" style="font-size: 18px;cursor:pointer;" fill="#757575" x="15" y="22">{collapsed-children-count}</text>';
