                    icon={FiMenu}
                    onClick={() => setSidebarOpen(true)}

                </div>

                <nav className="flex-1 p-2">
                    <SidebarLink
                        icon={FiHome}
                        label="Home"
                        onClick={() => {
                            nav.navigate('/');
                            setSidebarOpen(false);
                        }}
                    />

                    />
                </nav>

                <div className="p-4 border-t">
                    <button
                        onClick={handleLogout}
                        className="flex items-center gap-2 text-red-500"
                    >
                        <FiLogOut /> Logout
                    </button>
                </div>
            </Sidebar>

            {/* Main content */}
            <main className="flex-1 pb-16">
                {children}
            </main>

            {/* Tabbar */}
            <Tabbar>
                <TabbarItem
                    icon={FiHome}
                    label="Home"
                    active={location.pathname === '/'}
                    onClick={() => nav.navigate('/')}
                />
                <TabbarItem
                    icon={FiList}
                    label="Products"
                    active={location.pathname.startsWith('/products')}
                    onClick={() => nav.navigate('/products')}
                />
                <TabbarItem
                    icon={FiPlus}
                    label="New"
                    onClick={() => nav.navigate('/products/new')}
                />
                <TabbarItem
                    icon={FiSettings}
                    label="Settings"
                    active={location.pathname === '/settings'}
                    onClick={() => nav.navigate('/settings')}
                />
            </Tabbar>
        </div>
    );
};

// Helper component
const SidebarLink = ({ icon: Icon, label, onClick }) => (
    <button
        onClick={onClick}
        className="flex items-center gap-3 w-full p-3 rounded hover:bg-gray-100"
    >
        <Icon />
        {label}
    </button>
);
```

### Using the Layout

```javascript
// components/pages/private/ProductsPage/index.jsx
import { MainLayout } from '../../../layouts/MainLayout';
import { Block, List, ListItem } from '@cap-rel/smartcommon';

export const ProductsPage = () => {
    const products = [...];

    return (
        <MainLayout title="Products">
            <Block>
                <List>
                    {products.map(p => (
                        <ListItem
                            key={p.id}
                            title={p.label}
                            subtitle={`${p.price} €`}
                        />
                    ))}
                </List>
            </Block>
        </MainLayout>
    );
};
```

## Key Points to Remember

1. **Navbar** = top bar with title and actions
2. **Sidebar** = sliding side menu
3. **Tabbar** = bottom tab navigation
4. **useNavigation** = programmatic navigation
5. Combine these components into a **Reusable Layout**
