i going through recursive directive , came across following post helpful implement requirement. https://www.packtpub.com/books/content/recursive-directives. following code implement this. object editor directive template:
<div> <objecttree data-object="object" data-object-admin="objectadmin" data-folder-guid="folderguid" data-hide-header="'true'"></objecttree> <script type="text/ng-template" id="objecttree"> <div class="clear-left"> <h4 data-ng-if="!hideheader" data-ng-bind-template="{{objectadmin.displayname}}"></h4> <div data-ng-repeat="column in objectadmin.objectdefinition"> <div data-ng-switch="column.type"> <imageeditor data-ng-switch-when="image" data-image="object[column.name]" data-folder-guid="folderguid" data-column="column"></imageeditor> <formcheckbox data-ng-switch-when="boolean" data-input-value="object[column.name]" data-editable="column.editable" data-name="column.name" data-display-name="column.displayname" data-formname="'resourceaddeditformname'"></formcheckbox> <addresseditor data-ng-switch-when="address" data-address="object[column.name]" data-column="column" data-collection-admin="objectadmin"></addresseditor> <formtextbox data-ng-switch-when="string" data-ng-if="!column.isdropdown" data-input-value="object[column.name]" data-editable="column.editable" data-name="column.name" data-display-name="column.displayname" data-formname="'resourceaddeditformname'"></formtextbox> <dropdownbox data-ng-switch-when="string" data-ng-if="column.isdropdown" class="admin-textbox" data-selected-id-list="object[column.name]" data-dropdown="column" data-multiple="column.dropdowntypemultiple"></dropdownbox> <div data-ng-switch-when="object"> <hr/> <objecttree data-object="object[column.name]" data-object-admin="column" data-folder-guid="folderguid" data-hide-header="'true'"></objecttree> </div> <div data-ng-switch-when="array"> <hr/> <arrayobjecttree data-objects="object[column.name]" data-objects-admin="column" data-folder-guid="folderguid" data-hide-header="'true'"></arrayobjecttree> </div> </div> </div> </div> </script> </div> object tree:
app.directive("objecttree", ['$compile', '$templatecache', function ($compile, $templatecache) { return { restrict: "e", scope: { object: '=', objectadmin: '=', folderguid: '=', hideheader: '=' }, link: function (scope, element, attrs) { element.replacewith( $compile( $templatecache.get('objecttree') )(scope) ); } }; }]);
