+### 🧩 Group Rules (Prefix Aggregation)
+
+You can aggregate nodes by **package or prefix** using group rules. Rules can be configured:
+
+- **In UI** (group list)
+- **From backend** via `RegisterGroupRules` (recommended for production)
+
+Backend registration:
+
+```go
+import "github.com/pubgo/dix/v2/dixhttp"
+
+dixhttp.RegisterGroupRules(
+  dixhttp.GroupRule{
+    Name: "service",
+    Prefixes: []string{
+      "github.com/acme/app/service",
+      "github.com/acme/app/internal/service",
+    },
+  },
+  dixhttp.GroupRule{
+    Name: "router",
+    Prefixes: []string{"github.com/acme/app/router"},
+  },
+)
+```
+
+The UI will auto-load `/api/group-rules` if local rules are empty.
+
+### 🔎 Prefix Filter
+
+The toolbar provides a **Prefix Filter** field. It filters the current graph to show only nodes/providers
+whose package/type/function name contains the given prefix. This works in:
+
+- Providers/Types view
+- Type-focused dependency view
+- Group subgraph view
+
+### 🧭 Group Subgraph
+
+Click a virtual group node to open the **group detail panel**, then click **View group graph** to see:
+
+- Internal nodes
+- Upstream & downstream dependencies
+- Depth control applied from the toolbar
+

+### 🧩 分组清单（前缀聚合）
+
+支持通过**包路径/前缀**聚合节点，规则来源：
+
+- **前端分组清单**
+- **后端全局注册**（推荐生产使用）
+
+后端注册示例：
+
+```go
+import "github.com/pubgo/dix/v2/dixhttp"
+
+dixhttp.RegisterGroupRules(
+  dixhttp.GroupRule{
+    Name: "service",

+  },
+  dixhttp.GroupRule{
+    Name: "router",
+    Prefixes: []string{"github.com/acme/app/router"},
+  },
+)
+```
+
+当本地未配置分组清单时，前端会自动加载 `/api/group-rules`。
+
+### 🔎 前缀过滤
+
+工具栏提供“前缀过滤”，可按包路径/类型名/函数名过滤当前图：
