>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #2828681. --> Reported by: [mtnguru](https://www.drupal.org/user/1672174) Related to !32 >>> <h3 id="summary-problem-motivation">Problem/Motivation</h3> <p>The Book Navigation Block does not sort the list of books by weight.</p> <p>A weight can be assigned to the first page of a book through the outline tab, however it has no effect.</p> <p>I've created a patch and will submit it shortly. It's my first patch!</p> <p>NB: this concerns the order of <strong>multiple</strong> books, <strong>NOT</strong> ordering pages <em>within</em> a book.</p> <p><strong>Steps to Reproduce:</strong></p> <ul> <li>Enable the book module (it's in core)</li> <li>Create two books:</li> <li>Add content &gt; Book page &gt; <ul> <li> Title: 'My first book'</li> <li> Expand 'Book outline' settings - choose 'Create a new book'</li> <li> Then do the same for 'My second book'</li> </ul> </li> <li>Structure &gt; Block layout &gt; Add a Book navigation block in the sidebar<br> (Use the default settings.)</li> <li>Observe that it shows 'My first book' then 'My second book'</li> <li>Click the second book, Outline tab, change the weight to negative (so it should appear above book 1 in the list)</li> <li>Observe list is still in the same (wrong) order.</li> <li>Apply patch, refresh, order should have changed.</li> </ul> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Simple sort of books using sortByWeightElement.</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <p>- Write tests.</p> <h3 id="summary-ui-changes">User interface changes</h3> <p>None.</p> <h3 id="summary-api-changes">API changes</h3> <p>None.</p> <h3 id="summary-data-model-changes">Data model changes</h3> <p>None.</p>
