Interactive tree

One of the table component modes that allows you to navigate through a large hierarchical tree.

Configuring the Tree

To output data, you need to configure the table as follows.

1. SELECT 1 to return to the table of the following form:

declare   @result TABLE (id int, parentID int, name nvarchar(256), data nvarchar(max))

data - additional object data passed as a JSON line (quotation marks are required for parameters). If not used, pass an empty line.

parentID - reference to the element's parent. This field is used to build the hierarchy of elements (on the browser side).

2. In SELECT 3 specify ViewMode='dynamicTree' and plugin settings.

select 'dynamicTree' ViewType,
    	'{ 'levelDistance': 100, 'setCurrentAsRoot': false, 'orientation': 'top',
        'contHeight':'400px',
        'itemFormCode': 'tst-dynTreeItem',
        'itemFormContainer': '.itemFormDetails'
        }' dynamicTreeOptions

both the system settings of the jit plugin and additional settings are passed to dynamicTreeOptions:

setCurrentAsRoot - if true, when the element is clicked, the chart will be transformed (the root element becomes the currently selected one).
orientation - left, right, top, bottom - 'where' will the tree grow.
contHeight - you can set the height of the container. By default, the container has a height of 500px (with a width of 100%).
itemFormCode, itemFormContaiter - if these parameters are set, then when you click on the element, in the container with the selector itemFormContaiter будет добавляться форма с кодом itemFormCode, которой в качестве data-itemID будет передаваться id текущего элемента.

By default, the plugin's system settings (which you can replace with your own in dynamicTreeOptions) look like this:

var defaultOptions = {
                //id of viz container element
                injectInto: contID,
                //set duration for the animation
                duration: 800,
                //SET THE TREE TO VERTICAL
                orientation: 'left',
                //set animation transition type
                transition: $jit.Trans.Quart.easeInOut,
                //set distance between node and its children
                levelDistance: 50,
                //enable panning
                Navigation: {
                    enable: true,
                    panning: true
                },
                //set node and edge styles
                //set overridable=true for styling individual
                //nodes or edges
                Node: {
                    height: 25,
                    width: 60,
                    type: 'rectangle',
                    color: '#aaa',
                    overridable: true
                },

                Edge: {
                    type: 'bezier',
                    overridable: true
                },

                onBeforeCompute: function (node) {
                    as.vis.log('loading ' + node.name);
                },

                },

                //This method is called on DOM label creation.
                //Use this method to add event handlers and styles to
                //your node.
