Demo template for the language-tag picker on literal placeholders (nanodash PR #559). It shows all cases: 'name' has a restricted picker (en/de/fr) with default en and is repeatable (one name per language); 'comment' has an unrestricted picker with free BCP 47 entry (full tags like en-GB or de-CH can be typed) and, being optional, demonstrates that entering text without picking a language blocks submission; 'description' shows the picker on a long-literal textarea; 'regional name' has a restricted picker of full region-subtag languages (de-CH, de-DE, de-AT, fr-CH, it-CH) with no default; 'alternative label' has a fixed en tag for contrast (no picker).
