To empower anyone in the household to do the groceries, the grocery lists with all the details and the aisle information, need to be shared. This is supported via the Dropbox app.
To enable this feature, check the "Share grocery lists using Dropbox" checkbox. Once checked, the "Link to Dropbox" button will be available. Clicking on the button will call the Dropbox application if it is already installed on your device. Otherwise, it will navigate to the Dropbox web site. Either way, you will be asked for permission to allow the files to be shared using your Dropbox account.
Note that without a Dropbox account, the grocery lists cannot be shared. Please refer to the Dropbox web site for more information.
