How to get rid of the extra line on jstree's root node

Question

As you can see on the screenshot from a jstree,above the triangle on the first node there is an extra vertical dash line:

Anybody knows how to get rid of it?

Answer 1

In the version of jsTree I'm using, v3.3.7, the following call removes the dots...

$('#tree').jstree({
    core: {
        data: jsonData, // Some JSON data
        themes: { dots: false }
    }
});

The jsTree API documentation has specifications about this call.

Answer 2

With current version (3.3.3) you can remove dots directly by calling

$('#treeContainer').jstree().hide_dots()
