I have just created a complex map which is the menu structure for a map web export. I want to add to several maps but when I do it loses the layout and format from the original map. I want to retain this. How can I?
I think you have to customise the topics of the map before saving it as a web part, and change the required elements of the topic style and font to specific settings so that they are not automatically inherited from the map style. They are then preserved when the map part is inserted into a different map. But this could be a lot of detail to edit.
I have not tested whether it is sufficient to customise the style and font of the top level topic alone. This would be the first thing to try.
