Is there a way to hide the delete button on an array item? I basically just want an array of objects presented in a list and the user to be able to rearrange items but not delete them…
Only hiding the delete button is currently not possible within JSON Forms. There is a hacky workaround: You should be able to target the aria-label of the button and then hide it via CSS.
A clean solution is to register an own array renderer and then not render the delete button. You can start by looking at our array implementations: table and list.
