【问题描述】：

我正在使用角树。它工作正常，但分支时节点的间距不起作用......即它们都在直线上而不是彼此相距一定距离。我也在浏览器控制台上收到此错误。

Error: Lexer Error: Unexpected next character  at columns 36-36 [?] in expression ['level-' + 1 + (row.branch.selected ? ' active':'')].

这是我的 html 文件

<ul class="nav nav-list abn-tree">
 <li ng-show="header" class="nav-header">{{ header }}</li>
 <li ng-repeat="row in tree_rows | filter:{visible:true} track by row.branch.uid" ng- animate="'abn-tree-animate'" ng-class="'level-' + {{ row.level }} + (row.branch.selected ?  ' active':'')" class="abn-tree-row"><a id="{{ row.label }}" ng-  click="user_clicks_branch(row.branch)"><i ng-class="row.tree_icon" ng-click="row.branch.expanded = !row.branch.expanded" class="indented tree-icon"> </i><span   class="indented tree-label">{{ row.label }}</span></a></li>
</ul>

标签： css angularjs treeview

【解决方案1】：

你似乎在尝试使用我的angular-bootstrap-nav-tree。

该项目最近已更新，可以在 Bootstrap 2 或 Bootstrap 3 下正常工作，也可以与 Angular 1.1.5 或 Angular 1.2.0 一起工作（现在是 MIT 许可证）

现在有 4 个工作示例页面，使用这些不同版本的 Bootstrap 和 Angular。请再看一下——我相信你能做到。
