Details:

I want to create a drag and drop functionality, where I can go in Menubar and enter a submenu and then drag an object into a child in the window.

While I was able to drag and drop all kind of Objects in a window I wasn't able to make it work within the Menubar.

Thank you for your help

Minimal, Complete and Verifiable Example code:


    ImGui::BeginMenuBar();
    if(ImGui::BeginMenu("Menu")){
        ImGui::MenuItem("Item");
        if (ImGui::BeginDragDropSource(ImGuiDragDropFlags_None)) {
            ImGui::SetDragDropPayload("DND_DEMO_CELL", &taken, sizeof(int));
            SDL_Log("test works");
            ImGui::Text("Swap %s", taken);
            ImGui::EndDragDropSource();
            if (ImGui::BeginDragDropTarget()) {
                if (const ImGuiPayload *payload = ImGui::AcceptDragDropPayload("DND_DEMO_CELL")) {
                    IM_ASSERT(payload->DataSize == sizeof(int));
                        SDL_Log("Droped :%d", taken);
                    }
                }
                ImGui::EndDragDropTarget();
            }
        ImGui::EndMenu();
    }
    ImGui::EndMenuBar();
