Available Editing Restrictions
Element Lock Options
Apply restrictions to individual content blocks, entire rows, or both.
Click a content element and choose from these Element Lock settings:
Unlocked – Fully editable
Lock All – Prevents all edits
Hide All – Hides all components
Locked (Text Editable) – Locks design but allows text edits
Custom Restrictions
Click the gear icon next to the Element Lock toggle to enable Custom Restrictions.
Customize permissions for font, text color, alignment, and more. Each attribute supports:
Inherit – Uses parent settings
Editable – Can be changed
Locked – Not editable
Hidden – Locked and not visible
Image Size Restrictions
Add an image to your module. Scroll to the bottom of the image attributes section to:
Set exact dimensions
Set minimum or maximum dimensions
Text Character Limit
Add a text block to your module. Scroll to the bottom of the text attributes section. Set a maximum character count.
Alternate Text Settings
In the Optimize tab, choose how the module handles missing alt text:
Warning – Displays a warning
Ignored – Skips the check
Error – Blocks the module
This affects the accessibility impact score (High, Medium, or None).
Override Editor Restrictions
Users with the “Bypass Editor Restrictions” permission can override module locks while editing.
To override:
Click a locked module in the asset editor.
Toggle the Restriction switch to “On.”
You can control the default state of this switch in the self-service preferences.
Finalizing Changes
When finished:
Click the Actions menu in the module builder
Press Publish
This saves your restrictions and makes the module available for others.
Troubleshooting
Out-of-date modules can be updated even if they have no locked elements. Updates depend on the type of change and user permissions. For more information about updating out of date modules, check out our Using Modules in Assets help document.
Custom content (editable text, swapped images, etc.) is preserved and not overwritten.
Locked content is updated to match the latest module version, unless the user has admin override permissions.
Admin-only overrides are preserved only if the admin performs the update. If a non-admin updates the module, admin changes are lost.
Best practice: Lock layout sections and leave text editable. This allows updates to formatting without affecting team-created content.
