ImGui resizing window

vvvv gamma question
1

Hello, i m not arriving to obtain that ImGui rendered to a Entity>rootscene>scenewindow or a Renderer (stride) could changes the proportions of all its elements inside, to fit the new state of the window if i resize it ( lets say manually).
Is there any solution or elements given by imgui are defintively fixed by style padding fjob ? Thank you

is there anyway that imgui can be adapted to the window size ?
