AngularJS: tabela de árvore recursiva expansível
Estou a trabalhar na tabela recursiva da árvore de dados angular. Então a idéia é, jogar dados de árvore (sem conhecer o dept da árvore) e renderizar a árvore como uma tabela corretamente com o nó expansível. Neste momento, fiz com sucesso a tabela de árvore ao chamar o modelo recursivamente para criar uma tabela dentro da tabela
Aqui está o código ou você pode vê-lo em ação aqui: jsfiddle
<script type="text/ng-template" id="tree_item.html">
<tr style="width:100%">
<td><i class="fa fa-folder-open"></i></td>
<td>
{{data.name}}
<div id="expanded-data">
<table class="table table-striped" id="nested-table">
<div ng-repeat="data in data.nodes" ng-include="'tree_item.html'"> </div>
</table>
</div>
</td>
</tr>
</script>
<table class="table table-striped">
<thead>
<tr>
<th style="width:30px;"><i ng-click="loadItems()" class="fa fa-refresh blueicon"></i></th>
<th style="width:auto">Data tree</th>
</tr>
</thead>
<tbody ng-repeat="data in treeData" ng-include="'tree_item.html'">
</tbody>
</table>
Agora estou preso com o próximo passo, que é activar a opção Expandir e fechar quando você carregue no ícone da pasta e depois configure o nó-filho para mostrar = nenhum.
Tentei alguns com o ng-switch, mas sem sucesso. Vocês têm alguma ideia de como fazer isto ? Obrigado. 4

Adicionar ng-se aqui
<div id="expanded-data" data-ng-if="childrenVisible">
scope.toggleChildren = function () {
scope.item.childrenVisible = !scope.item.childrenVisible;
}
Editar: / / agora a mudar a pasta (aberta ou fechada) http://jsfiddle.net/8f3rL/35/

Podes considerar usar a grelha das árvores.
Demo: grelha expansível
<tree-gird tree-data="tree_data"></tree-grid>
Forneça uma árvore de dados estruturados, a definição de colunas e uma propriedade onde deseja expandir.
Forneça uma árvore de dados estruturados, a definição de colunas e uma propriedade onde você deseja expandir no seu controlador.
$scope.tree_data = [

children:[

$scope.col_defs = [

{ field: "DemographicId", displayName: "Demographic Id"},
{ field: "ParentId", displayName: "Parent Id"},
{ field: "Area"},
{ field: "Population"},
{ field: "TimeZone", displayName: "Time Zone"}

$scope.expanding_property = "Name";

Utilize esta tabela, com todas as operações CRUD e indentação amigável: -
