I have made strategic mistake and developed mashup omitting layouts.
I am looking into xml file in order to add lacking tags.
Could you suggest algorithm of doing this?
I have a panel with 5 labels, I would like to have 5 panels on responsive layouts.
Do you have any best practices of doing this?
Sergei, well, a way to go about this would be to go back to the Mashup editor screen, click on the Workspace tab, select the layer below 'Mashup' and then cut that. Insert your layout, add panels, and then paste your content back to one of them.
If you started with a static mashup layout, you may have to save off your current version to v1, delete the main mashup, create a new one with same name but set to responsive, then build your layout and start copy/pasting between v1 (saved static version) and the new responsive version.
