## Using another combination of backends?
The various examples above should reflect integration with a majority of backends, so you can follow the same logic.
Some backends require more information from you (e.g. in particular Vulkan and DirectX12 rendering backends). When in doubt, refer to the corresponding [examples](https://github.com/ocornut/imgui/tree/master/examples) application.

## Additional code to enable Multi-viewports mode
To use the [Multi-viewports](https://github.com/ocornut/imgui/wiki/Multi-Viewports) feature, pull the `docking` branch and enable the configuration flag:
```cpp
io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable;
```
At the end of your render loop, generally after rendering your main viewport but before presenting/swapping it:
```cpp
// Update and Render additional Platform Windows
ImGui::UpdatePlatformWindows();
ImGui::RenderPlatformWindowsDefault();
```
