Question

VSCode扩展开发，上下文菜单无法展开二级菜单，问题出在哪里？

extension.js:

function activate(context) {
    // 显示菜单
    const commandShowSubMenu = vscode.commands.registerCommand('vsmarketplace-badges.showSubMenu', () => {
        // 获取当前编辑器上下文
        const editor = vscode.window.activeTextEditor;
        if (!editor) {
            vscode.window.showErrorMessage('No active editor found');
            return;
        }
        
        // 展开右拉下一级菜单
        vscode.commands.executeCommand('editor.action.showContextMenu', 
            "subMenu1",
            "subMenu2",
            "subMenu3",
            "subMenu4",
            "subMenu5",
            "subMenu6",
            "subMenu7",
            "subMenu8",
            "subMenu9",
            "subMenu10",
            "subMenu11",
            "subMenu12")
    });

// 后面省略其他命令
