Choose a field type

Flashnerd currently supports 11 field types. Choose the type in the deck template, then enter each card's content in the card editor.

Add the right field

  1. Open Deck Detail → Deck Setting → Deck Template.
  2. Add a field or select an existing field's Field Type.
  3. Give it a meaningful name and choose its side.
  4. Set any defaults using the field's gear, then save the template.
  5. Open or add a card and fill in that field.

Cloze Deletion and Image Occlusion are Both Only types. They use the same content on both faces, with masking/reveal behavior, rather than separate question and answer values.

Shared settings

Every field supports the general Hidden setting. Card-level settings can follow Use Template Settings or use an override. Per-card Chinese/Japanese pronunciation overrides are available for applicable text.

A template can contain up to 20 fields. Deleting a field deletes its values from every card in that deck, so back up before restructuring a populated template.

See Field settings and card sides for inheritance, side placement, notes, and saving changes.
