Instead, the label is rendered as an <code>&amp;lt;h4&amp;gt;</code> inside a table header. The existing linker logic only attached to elements with <code>#title_display</code>, which doesn't apply to this table header structure.</p> <h3 id="proposed-resolution">Proposed resolution</h3> <p>Add handling in <code>canvas_stark_preprocess_field_multiple_value_form()</code> to render the linker alongside the <code>&amp;lt;h4&amp;gt;</code> in the table header when <code>#prop_link_data</code> is available on multiple-value field elements.</p> <p>This solution relies on <a href="https://drupal.org/i/3550848">#3550848</a> to prevent duplicate linkers from appearing on individual rows. That issue added a <code>titleDisplay !== 'invisible'</code> check in <code>DrupalFormElementLabel.tsx</code>. Since Drupal core sets <code>#title_display =&amp;gt; 'invisible'</code> for individual items in multi-value fields (see <code>WidgetBase.php</code> lines 207-213), the linker only renders once in the table header.</p> <h3 id="ui-changes">User interface changes</h3> <p>The linker will now appear for multiple-cardinality field widgets, allowing users to link multi-value fields to component properties.</p> <p>Demo of using with Tags field in standard profile<br> <img src="https://www.drupal.org/files/issues/2026-03-09/tags-linking.gif" alt="Linking to tags field"></p> > Related issue: [Issue #3552918](https://www.drupal.org/node/3552918)
