>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3581110. --> Reported by: [vipin.mittal18](https://www.drupal.org/user/319716) Related to !795 >>> <h3>Summary</h3> <p> Add support for <strong>List (Text)</strong> and <strong>List (Integer)</strong> prop types in Drupal Canvas, enabling builders to select predefined options in the UI based on backend configuration, following the existing multi-value prop patterns.</p> <h3>Problem / Motivation</h3> <p> Currently, while multi-value props are supported for several types, there is no consistent UI handling for List-based props (Text/Integer) where options are predefined.</p> <p>Builders defining List props in code components expect: </p><ul> <li>A clear selection UI in Canvas</li> <li>Enforcement of cardinality constraints</li> <li>Consistent behavior aligned with other multi-value prop types</li> </ul> <p>Without this, List props lack usability and consistency in the Canvas editor experience.</p> <h3>Scope</h3> <h4>In Scope</h4> <ul> <li>Support for: <ul> <li>List (Text)</li> <li>List (Integer)</li> </ul> </li> <li>Rendering predefined options in the UI (as configured in the code component)</li> <li>Enforcing cardinality constraints: <ul> <li>Cardinality = 1 &rarr; Single selection</li> <li>Cardinality &gt; 1 &rarr; Multi-selection (limited)</li> <li>Cardinality = unlimited &rarr; No selection limit</li> </ul> </li> <li>UI behavior aligned with existing multi-value prop implementations</li> <li>Read-only interaction model (selection only)</li> </ul> <h4>Out of Scope</h4> <ul> <li>Creating, editing, or deleting options from the UI (no CRUD)</li> <li>No backend schema or storage changes are included.</li> </ul>
