这是我想要生成多级导航的类别表迁移脚本。
注意：我使用“父”列生成多级菜单。
Schema::create('categories', function (Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->text('description');
$table->string('icon');
$table->tinyInteger('active')->default(1);
$table->integer('sort')->default(0);
$table->integer('views')->default(0);
$table->integer('parent')->default(0);
$table->timestamps();
$table->softDeletes();
});
使用最小循环生成主菜单，子菜单和子子菜单树的最佳方法是什么，在视图中使用会很好并且有用吗？
我想要实现的结果应该是以下，它是三级深度，用于生成3级导航。
