I downloaded phpgrid and installed on localhost to make some tests. At first I changed the language and then I wanted to change column names. After a lot of "look here-look there"s I finally found by chance that they could be done by changing the field names from the database table. But then I wanted to make ID field hidden but couldn't find how to do that. I checked all the titles here and FAQ and documentation. It's told that it can be done simply by adding some strings but I couln't understand what I will change, where I will write.
Or can we say we can't even make some basic changes because it's the free version?
