I am doing the registration part of a system, in this register it is possible to save several comments and edit them as we enter them or later, however it should work as follows, the user inserts the data, on the same screen , it clicks Include comments, (reinforcing with other words) when including these comments, it should not be stored directly in the database, since it must be saved in some type of cache until the user completes inserting all the other comments ( always clicking Include comments) and the other data and clicking Save.
Thank you in advance.
