Save a reusable local rule
- Build the card and field selection, conditions, missing-value behavior, and result action.
- Apply the rule to the current page and review a useful sample of matching, non-matching, and structurally different cards.
- Give the rule a name that explains its purpose, such as “Recent design posts” or “Products under 100.”
- Choose the page scope offered by the editor so the rule is not applied more broadly than intended.
- Save the rule. It appears in the Side Panel rule list and the complete rule library in Settings.
Rules, conditions, generated selectors, and settings are stored in Chrome’s local extension storage. Version 1 does not use an account or cloud synchronization.
Manual application or automatic application
Manual application
Return to the page, open Website List Filter, and apply the saved rule from the Side Panel. This gives you control over when the page view changes and does not require permanent access to every website.
Optional automatic application
Enable automatic application only when you want a rule to run on matching pages as they open. Chrome asks for access to the exact website origin covered by the rule. The broad optional host patterns in the manifest are only the upper bound for this runtime request; they do not grant all-site access during installation.
If access is declined or later removed, use the rule manually. When no active automatic rule needs an origin, the extension removes its dynamic registration and attempts to return that origin permission.
Dynamic lists and page navigation
On supported lists, the filter runtime observes newly added cards, including many infinite-scroll updates. A rule can also re-evaluate when the application changes its path without a full page load.
If the site replaces the whole list, moves content into an inaccessible interface, or changes the selected structure, the rule may need to be applied again or repaired. Automatic application is a convenience, not a guarantee that every future version of a website will preserve the same markup.
Repair a rule after a website layout change
- Open the saved rule and review its health or warning state.
- If the repeated group is no longer found, start card selection and choose a current representative card.
- If only one value fails, reselect that field inside the current card structure and keep the remaining conditions.
- Confirm the data type and missing-value behavior, then preview the repaired rule.
- Save only after matching and non-matching cards behave as expected.
The extension preserves usable parts of the rule where possible. Repairing a selector is safer than silently guessing after the page structure has changed.
Disable, restore, or delete
Disable a rule or use Restore to remove the extension’s current hiding, highlighting, and sorting changes. Delete individual rules in Settings, or remove all locally stored Website List Filter data when you no longer need it.
Website permissions are managed separately. Revoke them from Website List Filter Settings or Chrome’s extension site-access controls.
