TextareaFieldInput

Defined in: packages/core/src/fields/textarea/types.ts:51

Configuration input for a textarea() field.

Textarea fields store multi-line string values — bios, descriptions, internal notes, anything longer than a single-line text() field is comfortable holding. All properties are optional; unset properties fall back to the defaults listed below.

Defaults applied by textarea():

{
  type:     "textarea",
  label:    "",       // inferred from the field key by defineCollection
  required: false,    // field is optional by default
  rows:     4,         // visible textarea rows
  admin: {
    hidden:        false,   // visible in the admin form
    readOnly:      false,   // editable by default
    position:      "main",  // placed in the main content column, not the sidebar
    width: "100%",  // spans the full form width, not half
    cellAlignment: "left",  // text aligned left in the data table column
  }
}

Example

// Minimal — label is inferred from the key ("Bio")
bio: textarea()

// Required with length validation and a taller textarea
bio: textarea({ required: true, min: 10, max: 500, rows: 8 })

// Min/max with a custom error message
notes: textarea({ max: [280, "Keep it under 280 characters."] })
