Log in to your WordPress admin dashboard.
Navigate to Plugins → Add New Plugin.
Click Upload Plugin.
Select the Nexu Filter ZIP file.
Click Install Now.
Once installed, click Activate Plugin.
After activation, Nexu Filter will appear in your WordPress admin sidebar.
Nexu Filter requires an active, verified license to create or save filters.
Navigate to Nexu Filter → License.
Enter the license key provided after your purchase.
Click Activate.
Verify that the status displays License Active.
You can also check your license status and deactivate your license from this section when necessary.
To get started, navigate to Nexu Filter → Add Filter.
Filter Name
Enter a descriptive name to identify your filter in the WordPress dashboard.
AND / OR Logic
Choose how active terms should be combined:
OR: Displays content matching any of the selected terms.
AND: Displays content matching all selected terms.
Loop CSS Selector (Optional)
Connect your filter to a specific Post Loop Builder using a CSS class or ID.
Example: #services-loop
If left empty, Nexu Filter will target the first Oxygen loop located after the shortcode.
Tabs allow you to organize groups of categories and terms.
Click Add New.
Enter an internal name to identify the tab.
Define the visible tab label.
Select the categories or terms you want to include.
Enable the Active option to set the tab as the default selection.
You can add multiple tabs, reorder them by dragging, or remove tabs you no longer need.
Nexu Filter detects public taxonomies registered in WordPress, including those created with Secure Custom Fields (SCF).
Select the terms you want to include in each tab.
Once your configuration is complete, click Add Filter or Save Filter, depending on the action.
Navigate to Nexu Filter → Styles and select the filter you want to customize.
Nexu Filter allows you to configure tab buttons and category buttons independently.
| Style | Description |
|---|---|
| Square | Rectangular buttons |
| Pill | Fully rounded pill-shaped buttons |
| Square Outline | Rectangular buttons with an outline |
| Pill Outline | Rounded buttons with an outline |
| Text Only | Buttons without a visible container |
Colors
Configure default, hover, active, and background colors.
Typography
Choose the font family, size, and weight for each button group.
Spacing
Control the distance between buttons using the Gap setting, measured in pixels.
Styles are managed independently for tabs and categories, allowing you to establish different visual hierarchies.
Save your changes to apply them to the selected filter.
Navigate to Nexu Filter → Interaction and select the filter you want to configure.
Each tab includes an activation control and links associated with its terms.
These links use the ?filter= parameter followed by the term slug, allowing direct links to a compatible filter selection.
Limit the selection to one active category at a time.
When disabled, users can select multiple terms.
Hides categories that have no available items within the loaded content.
Hides tabs whose categories contain no available results.
Adds an optional All tab, used as the initial view to display all content.
Allows you to hide the control that clears all active filter selections.
After configuring these options, click Save Interaction.
Nexu Filter integrates with Post Loop Builder using a shortcode.
Open your page in Oxygen Builder and configure the Post Loop Builder with the content you want to display.
Make sure your posts have the appropriate categories or taxonomy terms assigned.
In WordPress, navigate to Nexu Filter → All Filters.
Find your filter and copy its shortcode.
Example:[nexo_filter id="123"]
The number 123 is for illustration purposes only. Use the actual ID of your filter.
Inside Oxygen Builder, add an element that supports WordPress shortcode execution.
Paste the shortcode and position it before the Post Loop Builder you want to filter.
If your page contains multiple Post Loop Builders, assign a CSS class or ID to the corresponding loop.
Then enter that selector in the Loop CSS Selector field in Nexu Filter.
This explicitly identifies which loop should respond to the filter.
Save your changes and open the published page.
Select different tabs and categories to verify that the results update correctly.
Nexu Filter uses the Isotope instance associated with Oxygen to reorganize the available elements.
Navigate to Nexu Filter → All Filters to view your existing filters and their shortcodes.
This section allows you to access, edit, or delete existing filters.
To modify a filter, open its configuration, make the necessary changes, and save.
You can reuse a filter through its shortcode in different compatible locations.
Nexu Filter works with elements that are already loaded on the page.
It does not load additional posts via AJAX.
This means:
Filtering happens without reloading the page.
Results update among the elements available in the loaded loop.
Posts from other pagination pages are not retrieved.
Native Oxygen Builder pagination is not modified.
To ensure complete results for a particular set of posts, consider how many elements the Post Loop Builder initially loads.
Verify that the shortcode is correct, the filter has configured tabs, and it has been inserted into an element that supports shortcodes.
Make sure you are using a compatible Post Loop Builder, your terms are correctly assigned, and the CSS selector points to the intended loop.
Check the Hide Empty Categories and Hide Empty Tabs options in the Interaction settings.
Navigate to License and verify that your license is active and verified. Version requires this condition to create or save filters.
This is expected behavior in Nexu Filter, which filters only the elements currently loaded on the page.
Nexu Filter is available in two licensing plans:
Individual License — 1 Website
Allows activation on one website.
Agency License — 10 Websites
Allows activation on up to ten websites.
Both plans include the same features.
Commercial Update Policy: Your purchase includes updates throughout the 1.x major version lifecycle, with no annual renewal required. Future major releases, such as Nexu Filter 2.0, require a new license.
For questions related to installation, license activation, compatibility, or Nexu Filter functionality, contact technical support.
