For example: + +```javascript + return h('textarea.twelve-word-phrase.letter-spacey', { + dataset: { + persistentFormId: 'wallet-seed', + }, + }) +``` + +That's it! This field should be persisted to `localStorage` on each `keyUp`, those values should be restored on view load, and the cached values should be cleared when navigating deliberately away from the form. + |
