You can access the Floormap under Configure App > Floormap.
Click Set Up Floor Map and the floor map editor window will then appear. Upload your floor map image in the section that reads "Click to Upload Floor Map." (Keep in mind that the floor map must be uploaded in .jpg, .jpeg, or .png format and must be at least 600 pixels by 600 pixels in size).
It is recommended you set up your Agenda Locations and Exhibitor Booth numbers beforehand as you will notice those will automatically appear in a list here!
Once the Locations are in, either from manually creating or from the Agenda/Exhibitor, you can click the pin icon next to the location name to drop it on the map. This will make your map accessible from the Agenda and the Exhibitor profiles if the locations/numbers match.
