Auto-saving Form system???

[woweya]

Hello, I have a Symfony UX Question.. I need to implement an auto-saving system for a Form so that, if the user accidentally closes the browser or refreshes the page, they won’t lose the changes made in the Form.
I was thinking of using cache and session to achieve this, together with a Stimulus Controller, but I have the impression that this might be a bit too much and that there could be a better way to achieve this goal...
Therefore, I’d like to ask what you would recommend.

Also, can Symfony UX “data-models” be dynamically mapped like: model_name_{id}?
