Angular Schema Form Multi Select Tree

This is an add-on for Angular Schema Form.

This is an adaptation of the angular-multi-select-tree.

Installation

The multi select tree is an add-on to the Bootstrap decorator. To use it, just include angular-schema-form-multi-select-tree.min.js after bootstrap-decorator.min.js.

You'll need to load the bootstrap CSS file to use multi select tree

• Bootstrap CSS

You can also install the module with bower $ bower install angular-schema-form-multi-select-tree

Usage

The multi select tree add-on adds a new form type, treeselect.

Form Type	Becomes
treeselect	a multi select tree widget

Schema	Default Form type
"type": "array"	Multi Select Tree

Select Only Leafs

The selectOnlyLeafs attribute disable the user to be able to select an entire set of data by selecting the parent category.

Max Items (Asynchronous Callback)

The maxItems attribute specifies the number of records we want to fetch during the callback.

Options

The options attribute contains all optional functionality.

Multiselect

You can specify if the widget allows multi-selection through the multiple option. By default the value is false.

options: {
    ...,
    multiple: true,
}

Select All

If you would like to be able to select all you can use the selectAll boolean. This will show a select all checkbox on top on the data. If you wish to specify what kind of data we are selecting you can specify the selectAllName string. This text will be added to the label of the checkbox.

options: {
    ...,
    selectAll: true,
    selectAllName: "All Advertiser"
}

Async Callback

Sometimes, we want to be able to fetch data asynchronously and introduce fields inter-dependencies.

Callback

You can register a callback through the "options.asyncCallback" attribute. The callback must be declared in the $scope defining the form.

$scope.getHierarchicalData = function () {
    // Definition
};

$scope.form = [
    {
        key: "Advertisers",
        type: "treeselect",
        ...
        options: {
            asyncCallback: "getHierarchicalData",
            ...
        }
    }
];

Dependencies

Multi Select Tree uses a system of events to introduce inter-field dependencies.

Register events

You can register an event to be thrown by the field after the user hit the "Done" button or closes the popup by clicking outside of it.

options: {
    ...,
    registerEvents: [
        "Advertisers"
    ],
}

Listen events

You can listen to specific events and assign an argument name to the data contained in the event for it to cascade in your callback.

options: {
    ...,
    listenEvents: [
        {
            name: "Advertisers",
            argName: "AdvertisersIds"
        }
    ]
}

Asynchronous Callback Definition

var callback = function (listenEventsArgs, {
    pageIndex: 0,
    maxItems: 100,
    query: "adv"
}) {
    // Definition
}

            }
