Textarea

The textarea field provides a multiline text input on forms and displays the saved text with line breaks on the Show view.

# app/avo/resources/post.rb
field :body, as: :textarea

By default, the input has five rows on the New and Edit views, and the field is hidden on the Index view.

Give longer text more room

Set rows to give longer text more room on the New and Edit views.

# app/avo/resources/post.rb
field :body, as: :textarea, rows: 10

Show the field on the index

The field has no built-in Index component. Follow the Generating a custom component for a field guide to add one before making the field visible there.
