We have a new project that is going to allow users to add their own nodes of a content type e.g. 'cars'.
There are some existing fields that they need to complete e.g. 'colour' and 'year'. We also need to allow them to add their own custom fields, which only they can use. So one user will add 'mileage' whereas another might want to add 'number of seats'. How would I go about allowing hundreds of users to do this without bloating the content type?
We will be building it in Drupal 7.
Thanks for any help.
