How to Build GSAP Draggable Cards in Webflow

This instructional module provides a comprehensive framework for engineering high-fidelity "swipe-to-toss" interactions within Webflow, replicating the tactile engagement found in physical card decks or instant photo galleries. By leveraging a "no-code" attribute-based system, the tutorial bridges the gap between complex JavaScript animation and visual development, enabling designers to implement sophisticated drag physics without writing code from scratch. The core value lies in its ability to transform static layouts into dynamic, satisfying user experiences suitable for portfolios and product showcases.

Viewers will learn to architect a robust HTML structure that manages absolute positioning and overflow behaviors to ensure a polished, glitch-free interface. The guide details the precise implementation of custom attributes (such as fc-dragable-card) to link UI elements—including wrappers, cards, and reset triggers—to the underlying interaction script. Furthermore, the specific configuration of CSS properties, such as pointer-events, is explained to ensure that the interactive stack does not obscure underlying functional elements like buttons.

By the conclusion of this lesson, users will achieve a fully scalable solution that integrates seamlessly with Webflow CMS Collections, utilizing structural selectors to apply dynamic styling variances like card tilt. The resulting component is fully responsive, optimizing the experience for mobile devices by adjusting wrapper dimensions and border styles. Additionally, users will understand how to granularly customize the interaction's physics—modifying rotation sensitivity, throw distances, and easing functions—through simple attribute adjustments to match their specific brand aesthetic.

• Essential Structural Hierarchy: To prevent layout issues, the parent section must utilize overflow: hidden to conceal tossed cards, while the card container requires position: relative to act as an anchor for the absolute-positioned card list.
• Attribute-Driven Interaction: The entire behavior is controlled via specific HTML attributes, primarily fc-dragable-card="wrapper" for the container, component for the cards, and reset for the restoration button, allowing for a "plug and play" implementation.
• Strategic Pointer Events Management: To ensure usability, pointer-events: none is applied to the gallery list wrapper so clicks pass through to the buttons below, while pointer-events: auto is reapplied to individual cards to maintain their interactivity.
• CMS Integration via Pseudo-Selectors: When applying this effect to dynamic CMS collections, manual combo classes are replaced with structural selectors (such as odd and even items) to programmatically generate the alternating rotation tilt for a natural stack appearance.
• Granular Physics Customization: The interaction's "feel" can be fine-tuned without code by adding optional attributes to the component, allowing control over variables such as throw distance (default 1000px), rotation sensitivity (default 45°), and easing functions.

• 01:12 – Adding the CC overflow hidden combo class to the section element to prevent horizontal scroll bars when cards are tossed off-screen.
• 02:26 – Setting position: relative on the gallery outer wrapper to serve as an anchor for the absolutely positioned card container.
• 02:58 – Applying the attribute FC-dragable-card="wrapper" to the gallery outer wrapper to define the active drag zone for the script.
• 03:51 – Changing the reset element’s HTML tag from a link to a button in the settings panel.
• 03:58 – Adding the attribute FC-dragable-card="reset" to the button element to connect it to the restoration logic.
• 04:19 – Setting position: absolute with zero offsets on the gallery list wrapper to force it to fill the parent container.
• 04:33 – Setting pointer-events: none on the list wrapper so that clicks pass through to the buttons located beneath the stack.
• 05:14 – Re-applying pointer-events: auto to individual gallery list items to ensure the cards themselves remain interactive and draggable.
• 05:56 – Adding the critical attribute FC-dragable-card="component" to the gallery list items to initialize them as draggable objects.
• 07:01 – Activating GSAP and the draggable plugin within the project settings to enable the physics engine.
• 09:29 – Configuring optional custom attributes (e.g., FC dragable card rotation) to adjust physics variables like rotation sensitivity.
• 13:32 – Using structural selectors (e.g., Last Item, Even Item, Odd Item) on CMS collections to apply alternating rotation values programmatically.

How to Build Draggable Swipe-to-Toss Cards

Technical Documentation & Implementation Guide

This guide outlines the precise HTML structure, CSS positioning, and custom attributes required to implement the "swipe-to-toss" interaction.

1. Configure the Parent Section

• How: Select your main Section element and add a combo class (e.g., CC overflow hidden). Set the Overflow property to hidden.
• Why: When a card is "tossed," it physically moves outside the section boundaries. Without this setting, throwing a card would trigger an unwanted horizontal scroll bar or show the card floating awkwardly outside the layout.

2. Set Up the Outer Wrapper

• How: Create a div called Gallery Outer Wrapper. Set it to Display: Flex (Align: Center) and give it a specific height (e.g., 80vh). Crucially, set its Position to Relative.
• Why: This wrapper centers the content. It must be Relative so that the card container (which will be absolute) has a parent anchor to latch onto.

3. Define the Interaction Zone

• How: With the Gallery Outer Wrapper selected, go to the Element Settings panel and add the custom attribute: fc-dragable-card="wrapper".
• Why: This attribute identifies the specific boundary of the interaction for the script, grouping the cards and the controls together.

4. Create the Reset Trigger

• How: Inside a buttons wrapper, place a button element (ensure it is a <button> tag, not a link block). Add the attribute: fc-dragable-card="reset".
• Why: This connects the button to the script's restoration logic, allowing the user to recall all tossed cards back to the stack.

5. Position the List Wrapper

• How: Create a Gallery List Wrapper inside the outer wrapper. Set Position to Absolute and set all offsets (Top, Right, Bottom, Left) to 0. Additionally, set Pointer Events to None.
• Why: Absolute positioning forces the wrapper to fill the parent container. Setting pointer events to "none" allows user clicks to pass through this layer to reach the buttons located physically behind the card stack.

6. Configure Individual Card Items

• How: Select the Gallery List Item. Set Position to Absolute (to stack them) and height to 100%. You must set Pointer Events back to Auto.
• Why: Absolute positioning ensures the cards stack directly on top of one another rather than listing vertically. Re-enabling pointer events is critical; otherwise, the cards would inherit "none" from the parent and become un-clickable and non-draggable.

7. Apply Static Card Tilt (Static Method)

• How: For static elements, add combo classes like CC-odd or CC-even to your list items. Apply a slight rotation (e.g., 3deg and -3deg) to these classes, leaving the top card centered.
• Why: This creates a messy, organic "stacked deck" aesthetic rather than a perfectly rigid pile.

8. Initialize the Draggable Component

• How: Select the Gallery List Item and add the attribute: fc-dragable-card="component".
• Why: This is the primary trigger that tells the underlying script, "This specific element is a draggable card." The script will automatically apply default physics to any element with this attribute.

9. Activate the Physics Engine

• How: In your project settings, ensure you have activated GSAP and the Draggable plugin.
• Why: The interaction relies on the GSAP library to handle the complex math of throwing, dragging, and inertia. It will not function without these libraries loaded.

10. Customize Physics (Optional)

• How: To change the default interaction "feel," add optional attributes to the component, such as:‍
  
  • fc-dragable-card-throw-distance (Default: 1000px)‍
  • fc-dragable-card-rotation (Default: 45deg)‍
  • fc-dragable-card-throw-duration (Default: 0.5s).

• Why: This allows you to fine-tune the sensitivity and animation style (e.g., how far a card flies or how much it spins) without writing custom code.

11. Implement via CMS (Dynamic Method)

• How: When using a CMS Collection, you cannot use manual combo classes for tilt. Instead, use Webflow's Structural Selectors. Select the Collection Item, choose "Even Item" (apply -3deg rotate) and "Odd Item" (apply 3deg rotate).
• Why: Structural selectors allow you to programmatically style alternating items in a dynamic list, ensuring the "stacked" look is preserved regardless of how many items the CMS generates.

To construct this interface, create a relative parent container with the attribute fc-dragable-card="wrapper" and nest absolutely positioned card elements inside featuring the fc-dragable-card="component" attribute. Ensure you activate the GSAP Draggable plugin in your project settings to enable the physics engine without writing custom JavaScript.

You can fine-tune interaction mechanics by adding specific HTML attributes to your draggable component, such as fc-dragable-card-throw-distance (defaulting to 1000px) and fc-dragable-card-rotation. These attributes allow you to control variables like throw duration, rotation sensitivity, and easing functions directly from the element settings panel.

Apply the CSS property pointer-events: none to the absolute wrapper covering your buttons so that clicks pass through to the underlying layer. You must then strictly re-apply pointer-events: auto to the individual child elements (the cards) to ensure they remain interactive and draggable while the container itself ignores pointer activity.

Instead of manual combo classes, utilize Webflow's structural selectors on your Collection Item class to style dynamic content based on its index. Select "Even Item" and "Odd Item" from the selector dropdown to apply opposing rotation values (e.g., 3° and -3°), automatically generating a natural, stacked appearance for your list.
