# `PhiaUi.Components.WeekPicker`
[🔗](https://github.com/charlenopires/PhiaUI/blob/v0.1.17/lib/phia_ui/components/calendar/week_picker.ex#L1)

Week selection input — styled native `<input type="week">`.

Wraps the browser's native week picker with PhiaUI's input styling (borders,
focus ring, size variants, error state). Supports standalone use or
Phoenix form field integration with changeset error display.

The value format follows the ISO 8601 week notation: `"YYYY-Www"` (e.g. `"2026-W10"`).

Present in scheduling and reporting UIs: Mantine `WeekPicker`, Ant Design
`DatePicker` (picker="week"), MUI `DatePicker` with week view.

Zero JavaScript — uses the native browser week control.

## Examples

    <%!-- Standalone --%>
    <.week_picker id="report_week" name="report_week" label="Reporting Week" value="2026-W10" />

    <%!-- With min/max constraint --%>
    <.week_picker id="sprint" name="sprint" min="2026-W01" max="2026-W52" />

    <%!-- Form field integration --%>
    <.week_picker
      id="event_week"
      name={@form[:week].name}
      value={@form[:week].value}
      errors={Enum.map(@form[:week].errors, &translate_error/1)}
      label="Event Week"
    />
