How to integrate Finsweet Webflow Hacks with Webflow

Finsweet Webflow Hacks add specific functionality that Webflow doesn't provide natively, like advanced CMS filtering, custom form behaviors, or dynamic content based on URL parameters. Code executes in visitors' browsers (client-side) without requiring server configuration or API authentication.

You can integrate Finsweet Webflow Hacks using three approaches. First, copy JavaScript code into your project's custom code sections in Site Settings. Second, configure specific page elements with classes or attributes that target the hack functionality. Third, clone working examples from the showcase site to see proper implementation patterns.

Note that Finsweet Webflow Hacks are built with legacy jQuery and many features have been superseded by Finsweet Attributes and Hacks in TypeScript, which are actively maintained and recommended for new projects.

Copy code into Webflow custom code sections

Navigate to Site Settings → Custom Code in your Webflow project. Each hack provides complete JavaScript code that you paste into either the Head Code or Footer Code sections, depending on when the script needs to run.

Implementation steps:

Open the specific hack page for the feature you need
Locate the code breakdown section with the code snippet
Click the Copy code button to copy the complete script
Paste into Site Settings → Custom Code, typically in Footer Code unless the hack's documentation specifies otherwise
Publish your site to activate the code

Critical requirements: Hacks only work on published Webflow sites. Preview mode won't show functionality because scripts operate on rendered HTML (the final HTML code browsers display after Webflow processes your components), not components in the editor. Always publish before testing.

For most legacy jQuery Hacks, place scripts in Site Settings → Custom Code → Footer Code (not page-level Code Embed elements) so they run after the DOM loads and can use Webflow's built-in jQuery. Some hacks may specify Head Code placement in their documentation.

Script placement considerations: Place code in Site Settings → Custom Code, typically in Footer Code for jQuery Hacks. Footer placement ensures scripts run after the DOM loads and avoids blocking page rendering.

Webflow includes jQuery by default, so you typically don't need to add it separately. Global placement in Site Settings ensures scripts load correctly and initialize before interacting with page elements.

Configure elements with classes or attributes for hack targeting

Legacy Finsweet Webflow Hacks typically identify which page elements to modify through specific CSS classes you add in Webflow. Modern Finsweet Attributes solutions use custom HTML attributes with fs- prefixes. After adding hack scripts to custom code sections, you mark specific elements with the classes or attributes documented on each hack's page.

For legacy jQuery Hacks:

Select any element in Webflow and add the CSS class specified in the hack's documentation. For example, Hack #4 for dynamic anchor links uses classes like .hack4-filter-button and .hack4-cms-anchor-section to identify which elements to target.

For Finsweet Attributes solutions:

Select any element in Webflow, open the Element Settings panel, and scroll to the Custom Attributes section. Add the attribute name and value specified in the Attributes documentation. Attributes use the fs- prefix pattern for identifying elements.

Testing workflow:

Add required CSS classes or HTML attributes in Webflow
Publish your Webflow site (not just preview)
Visit the live published URL
Test functionality in production environment
Clear browser cache if changes don't appear immediately

Considerations: Class names and attribute names are case-sensitive and must match the documentation exactly. Start with a single solution on a minimal page to isolate any conflicts before adding multiple features. Always follow the selectors documented on the specific hack or Attributes solution page.

Clone working examples from showcase site

Access the clonable project template via the Webflow showcase page to explore working hack examples. The showcase describes Webflow Hacks as "a series of YouTube video walkthroughs and fully commented custom-code 'hacks' for Webflow, presented as a clonable project."

Clone workflow:

Visit the Made in Webflow showcase page
Click Clone to copy the project to your Webflow account
Explore individual hack pages to see implementation details
Inspect elements to view class configurations and code structure
Copy code snippets from the hack pages
Adapt the patterns to your own projects

Each hack page in the cloned project includes working examples of the functionality, complete code snippets ready for copy-paste, video walkthroughs demonstrating installation, and technical explanations of code functionality.

Reference the cloned project when implementing hacks in your production sites. The working examples at the Finsweet Hacks demonstration site show proper script placement, selector syntax, and element structure.

Combine multiple hacks: The showcase demonstrates how multiple hacks coexist on the same site without conflicts. Use unique identifiers when running similar features multiple times on one page.

What you can build

Integrating Finsweet Webflow Hacks with Webflow lets you build advanced functionality using client-side JavaScript utilities.

Personalized landing pages: Create dynamic marketing pages that display "Welcome back, Sarah!" headlines and role-specific CTAs when visitors arrive via email links containing ?firstname=sarah&role=manager parameters. Show "Analytics Dashboard Demo" content for ?product=analytics visitors and "Marketing Automation Demo" for ?product=automation visitors from different ad campaigns
CMS collection filtering: Build filterable collections using Finsweet Attributes CMS Filter, which provides actively maintained multi-select filtering, live result counts, and AND/OR logic for complex filtering scenarios like showing only projects tagged with both "fintech" AND "branding" AND "2024"
Multi-step qualification forms: Create progressive forms that reveal fields conditionally based on previous answers, such as a service inquiry form that shows pricing options only after visitors select their company size and requirements
Interactive calculators: Build ROI estimators, pricing tools, or financial calculators entirely within Webflow, like a mortgage calculator that updates monthly payments as visitors adjust loan amount, interest rate, and term length sliders

Frequently asked questions

What's the difference between Finsweet Attributes and Finsweet Webflow Hacks?
Finsweet Webflow Hacks is the original collection of over 50 custom code snippets built with jQuery and TypeScript for extending Webflow functionality. Finsweet Attributes is the newer, more robust library that replaced many of the original hacks with attribute-based solutions requiring less custom code.
Finsweet Attributes work by adding a single script tag and configuring HTML attributes in Webflow's Designer. Finsweet Webflow Hacks require copying individual JavaScript snippets for each feature.
For new projects, use Finsweet Attributes for CMS filtering, loading, and nesting — these solutions handle over 200 million monthly loads and receive active updates. Use Finsweet Webflow Hacks for specialized functionality not covered by Attributes, like custom form behaviors, URL parameter manipulation, or device-specific scripts.
Both approaches integrate through Webflow's custom code sections in Site Settings and work alongside each other without conflicts.
Why don't Finsweet Webflow Hacks work in Webflow's Designer preview?
Finsweet Webflow Hacks operate on published HTML, not Designer components. The Webflow Designer provides a preview environment that doesn't execute custom code the same way live sites do.
Scripts in Site Settings → Custom Code only run after publishing. Publish your Webflow project and test functionality on the live published URL. The Finsweet forum confirms this is the expected behavior; JavaScript in custom code sections requires a published environment to interact with rendered DOM elements properly.
Clear your browser cache (Cmd+Shift+R or Ctrl+Shift+F5) if changes don't appear immediately after publishing. Ad blockers and privacy browser extensions can also interfere with script loading. For Finsweet Webflow Hacks specifically, you must publish your site and test on the live URL—changes will not appear in Webflow's Designer preview mode.
How do I filter CMS collections with date ranges using Finsweet Hacks?
Date filtering requires normalizing date formats because locale differences cause inconsistent filtering across devices.
Use ISO-8601 format (YYYY-MM-DD) in your CMS date fields for consistent parsing across different locales and devices. Add this JavaScript to normalize date inputs before filtering to ensure compatibility:
// Convert any date string to ISO format const normalizeDate = (dateString) => { const date = new Date(dateString); return date.toISOString().split('T')[0]; };
The original CMS Filter hack (#5) has been deprecated in favor of Finsweet Attributes CMS Filter, which provides more reliable filtering capabilities including better date range handling. For production sites, use Finsweet Attributes CMS Filter with proper date field configuration in your Webflow CMS collections.
Can I use Finsweet Hacks with Webflow's native interactions?
Yes, but dynamically loaded content requires reinitialization. Webflow's native interactions don't automatically attach to elements loaded after page render, like items added through "Load More" buttons or infinite scroll. Finsweet CMS Load offers a workaround through its 'Reset Interactions' option to reinitialize Webflow interactions on newly rendered items.
Webflow Interactions don't work on dynamically loaded CMS items. Use the 'Reset Interactions' option in Finsweet CMS Load to reinitialize Webflow interactions on newly rendered CMS items.
For custom implementations, call Webflow.require('ix2').init() after loading new content. This resets Webflow's interaction engine and attaches animations to dynamically added elements.
However, this approach has a known limitation: Webflow Interactions do not work on dynamically loaded CMS items by default. To resolve this, use Finsweet CMS Load's 'Reset Interactions' option to reinitialize Webflow interactions on newly rendered items. Static page content with Finsweet Webflow Hacks works without additional configuration.
How do I implement multiple filters on the same Webflow page?
Each filter instance needs a unique identifier to prevent initialization conflicts. Duplicate IDs cause scripts to initialize the first instance only and ignore subsequent ones.
Add unique attribute values to each filter group:
First filter: fs-cmsfilter-id="filter-1"
Second filter: fs-cmsfilter-id="filter-2"
Third filter: fs-cmsfilter-id="filter-3"
Apply the identifier to the Collection List wrapper and corresponding filter form. All elements within each group inherit the identifier automatically, keeping filter logic isolated.
Test with a single filter first to confirm basic functionality, then add additional instances incrementally.
