インライン編集

<%# Markup for the editable (inline editing) demo.
    Click / Enter / F2 on the display element (a button) enters edit mode, focusing the
    input and selecting all. The library handles mode switching (data-mode), focus /
    select-all, and the commit event; the look lives in demo.css.
    Two variants are shown:
      1. Single-line <input>: Enter saves, Escape cancels.
      2. Multiline <textarea>: Enter inserts a newline, Ctrl+Enter saves, Escape cancels.
    submitOnBlur=true also saves on blur for both. %>
<div class="editable-demo">
  <%# 1. Single-line inline edit. %>
  <div class="editable" data-controller="stimeo--editable"
       data-stimeo--editable-submit-on-blur-value="true">
    <span class="editable__hint"><%= t("components.editable.demo.hint") %></span>
    <button
      type="button"
      class="editable__display"
      aria-label="<%= t("components.editable.demo.aria_label") %>"
      data-stimeo--editable-target="display"
      data-action="click->stimeo--editable#edit keydown->stimeo--editable#onDisplayKeydown">
      <%= t("components.editable.demo.value") %>

    <input

      data-stimeo--editable-target="input"
      data-action="keydown->stimeo--editable#onKeydown blur->stimeo--editable#onBlur" />
  </div>

  <%# 2. Multiline inline edit. The controller detects the <textarea> and treats Enter as a
      newline, so saving is Ctrl+Enter (or blur). The display uses white-space: pre-line so
      saved line breaks render. %>
