See #211 (mostly the lower posts).

There is a function ImGui::PushItemFlag(ImGuiItemFlags_Disabled, true); in the imgui_internal.h (non-public) API which you may use. It's however not finished and doesn't affect visuals at all, so the widgets won't become grey.

Currently you may do something like that:

    static bool disabled = false;
    ImGui::Checkbox("Disable", &disabled);
    if (disabled)
    {
        ImGui::PushItemFlag(ImGuiItemFlags_Disabled, true);
        ImGui::PushStyleVar(ImGuiStyleVar_Alpha, ImGui::GetStyle().Alpha * 0.5f);
    }
    [...]
    if (disabled)
    {
        ImGui::PopItemFlag();
        ImGui::PopStyleVar();
    }
