<p><strong>Description<br>
</strong><br>
In fields where multiple cardinality is enabled, an issue is observed in the existing 1.x UI behavior.</p>
<p>When a user enters a value in a multi-value field, the system automatically creates the next row without requiring any explicit user action (such as clicking “+ Add New”). Along with this, a row weight field appears automatically, even though no reordering interaction has been performed.<br>

<p><strong>Acceptance Criteria<br>
</strong>
</p><ul>
<li>
<strong>No Automatic Row Creation</strong>
<ul>
<li>Given a multi-cardinality field</li>
<li>When a user enters a value in a row</li>
<li>Then a new row should <strong>not</strong> be created automatically</li>
<li>And a new row should only appear when explicitly triggered (e.g., via “Add another item” action)</li>
</ul>
</li>
<li>
<strong>Row Weight Visibility Control</strong>
<ul>
<li>Given a multi-cardinality field</li>
<li>When the user has not initiated any reordering action</li>
<li>Then the <strong>row weight field should not be displayed</strong></li>
</ul>
</li>
<li>
<strong>Consistent Behavior with New UI</strong>
<ul>
<li>The behavior of multi-cardinality fields in 1.x should align with the new UI implementation</li>
<li>No unexpected UI elements (extra rows or weights) should appear</li>
</ul>
</li>
<li>
<strong>User Interaction Driven Actions</strong>
<ul>
<li>All additional rows and reordering controls should be <strong>user-initiated only</strong></li>
<li>No implicit triggers based on value entry</li>
</ul>
</li>
</ul>
