Problem:
The header menu on your site disappears or is hidden when it is longer than the width of the page.
Reason:
If the Responsive Website option is enabled in your site's Theme builder and your header menu is longer than the width of the page, ShortPoint will automatically display the collapsed Mobile navigation. ShortPoint automatically displays the collapsed navigation so that some of your navigation links are not hidden when it is longer than the width of the page.
Solution:
Please follow these simple steps to resolve the issue,
1. Please copy the CSS code snippet below,
html.shortpoint-force-sharepoint-responsive.shortpoint-mobile-menu-off #DeltaTopNavigation .ms-core-listMenu-root { width: 768px !important; }
2. Go to ShortPoint's dashboard page and open Theme builder
3. Navigate to Utilities > Custom CSS and paste the copied CSS in the textarea
4. Click Publish and the issue should be resolved.
