求识别CustomTkinter中该组件的名称及使用方法

你截图里的组件是CTkCollapsibleFrame，它是CustomTkinter的常用扩展组件（部分场景需单独安装对应扩展包，也可通过基础组件手动实现），核心作用是创建可展开/折叠的分层导航面板，适配GUI的侧边菜单需求。

基础使用示例（依赖扩展包） #

import customtkinter as ctk
from customtkinter import CTkCollapsibleFrame

# 先安装扩展包：pip install customtkinter-collapsibleframe

ctk.set_appearance_mode("dark")
ctk.set_default_color_theme("blue")

app = ctk.CTk()
app.geometry("450x550")

# 创建侧边容器
sidebar = ctk.CTkFrame(app, width=220)
sidebar.pack(side="left", fill="y", padx=8, pady=8)

# 可折叠菜单：Dashboard
dashboard_menu = CTkCollapsibleFrame(sidebar, text="Dashboard")
dashboard_menu.pack(fill="x", padx=5, pady=5)
# 添加子选项
ctk.CTkButton(dashboard_menu, text="Overview").pack(fill="x", padx=12, pady=3)
ctk.CTkButton(dashboard_menu, text="Analytics").pack(fill="x", padx=12, pady=3)

# 可折叠菜单：Orders
orders_menu = CTkCollapsibleFrame(sidebar, text="Orders")
orders_menu.pack(fill="x", padx=5, pady=5)
ctk.CTkButton(orders_menu, text="Pending").pack(fill="x", padx=12, pady=3)
ctk.CTkButton(orders_menu, text="Completed").pack(fill="x", padx=12, pady=3)

app.mainloop()

手动实现方案（无需扩展包） #

如果不想依赖第三方扩展，可通过CTkFrame和CTkButton结合组件的显示/隐藏方法手动实现折叠逻辑：

import customtkinter as ctk

ctk.set_appearance_mode("dark")
ctk.set_default_color_theme("blue")

app = ctk.CTk()
app.geometry("450x550")

sidebar = ctk.CTkFrame(app, width=220)
sidebar.pack(side="left", fill="y", padx=8, pady=8)

# 定义折叠切换函数
def toggle_submenu(subframe):
    if subframe.winfo_ismapped():
        subframe.pack_forget()
    else:
        subframe.pack(fill="x", padx=12, pady=3)

# Dashboard菜单
dashboard_btn = ctk.CTkButton(sidebar, text="Dashboard", command=lambda: toggle_submenu(dashboard_sub))
dashboard_btn.pack(fill="x", padx=5, pady=5)
dashboard_sub = ctk.CTkFrame(sidebar)
dashboard_sub.pack(fill="x", padx=12, pady=3)
ctk.CTkButton(dashboard_sub, text="Overview").pack(fill="x", padx=10, pady=3)
ctk.CTkButton(dashboard_sub, text="Analytics").pack(fill="x", padx=10, pady=3)

app.mainloop()
