I copied the party app and was trying my hand in editing it while I came across this problem. IN the feature that allows users to add items, there is no option to add location to your items. Is it just me or I am just not able to find it?
The templates are what they are. Feel free to add that functionality. You may have to modify the Google Sheet and add some columns. Then add the appropriate edit components.
I read your answer and played with the options. Seems that there is no such option exactly but typing a location automatically displays a map. Thanx
