Problem: accidentally pressing 'Esc' when editing a form in a "standard" LiveView modal dialog will discard all edits.

Proposed solution: Make the modal show a confirmation window on close when there have been changes on the form.

LiveView v0.20 was used.

Table of content

• Making LiveView modal show confirmation on close
• Using updated modal in a CRUD LiveView
