Problem description

The hidden fields in repeater and builder do not save their value to database, and an empty div is displayed in the html of the page.

Expected behavior

The values of the hidden fields should be saved as usual.

Steps to reproduce

1. Create a repeater with a hidden field.
2. Add the item to repeat.
3. Save and check the database.

The values from the hidden field will not be in the database.

@indigoram89 Based on a Discord message from a Filament core team member:

->hidden() removes the field completely from the form. Whereas a Hidden::make() will create a hidden input. But seeing as this has to do with cost it is best to handle this as Leandro suggested on the backend. Hidden inputs can be manipulated on the front end.

This message is 2 years old but I check and ->hidden() indeed disables the rendering of the DOM element while the Hidden component simply renders and hides the field. Strange though how this is not mentioned in the documentation (or at least I can't find anything about it).
