i want/need a database that works when not connected to the web that can store two fields, one of them would be a list. Keeping the same tag I want to add more values to these fields. Basically two columns lots of rows, I'm hoping it can be done with lists?
Use the tinydb
I don't know how to add list to a list
Have you considered using an offline database? Seems like your requirement would be met:
