How to Add a Scrolling Alert Bar to a SharePoint Wiki Page

Product: SharePoint Online
Device & OS: not provided
Scenario: Attempting to insert custom HTML or scripts to create a scrolling alert bar on a SharePoint wiki page.

Solution 1Recommended

Enable Custom Scripting and Publishing Features

Activate the necessary backend settings and publishing features to make the Content Editor and Script Editor web parts visible on classic SharePoint pages.

In SharePoint, security settings disable custom scripts by default. To use the Content Editor or Script Editor web parts for your scrolling alert bar, you must manually enable custom scripting at the site level and activate the required publishing features.

Enable Custom Script

Activate Site Collection Feature

Navigate to your site, click the gear icon to open 'Site Settings', select 'Site Collection Features', and click 'Activate' next to the 'SharePoint Server Publishing Infrastructure' feature.

Activate Site Feature

Go back to 'Site Settings', select 'Manage Site Features', and click 'Activate' next to the 'SharePoint Server Publishing' feature.

Insert the Web Part

Return to your classic wiki page, click 'Edit', go to 'Insert' > 'Web Part', and select the Script Editor or Content Editor to embed your scrolling alert bar code.

Enable Custom Scripting and Publishing Features

Modern SharePoint Page Compatibility: If you are using modern SharePoint pages, these classic web parts will remain unavailable. You will need to use a custom SharePoint Framework (SPFx) Script Editor web part instead.

Frequently Asked Questions

Why are the Content Editor and Script Editor web parts missing in SharePoint?

These web parts are hidden by default when custom scripting is disabled for security reasons, or if the necessary SharePoint Server Publishing features have not been activated on your site collection.

Can I use the Script Editor web part on modern SharePoint pages?

No, modern SharePoint pages do not support the classic Script Editor web part natively. To inject custom scripts on a modern page, you must deploy a custom SharePoint Framework (SPFx) web part.

Do I need administrator permissions to enable custom scripts?

Yes, enabling custom scripting and activating site collection publishing features requires SharePoint Administrator or Site Collection Administrator permissions.
