How can I make my CMS Сollections in Webflow open a popup to view details instead of loading a separate page? I have been unable to find a solution.

To display CMS Collection item details in a popup instead of navigating to a separate page, you need to use a combination of Collection Lists, Interactions, and a hidden detail modal inside the same page. Here's how to set it up.

​

1. Set Up Your CMS Collection List

​

• Add a Collection List to your page and connect it to your desired CMS Collection.
• Inside each item, include a summary preview (e.g., thumbnail, title).
• Add a button or div that users will click to open the popup.

​

2. Design the Popup Modal

​

• Create a div block outside the Collection List. This will serve as your popup/modal container.
• Set this modal to position: fixed, display: none, and z-index: high. Apply a background overlay if needed.
• Inside this modal, add text/image blocks with static elements that will get filled dynamically via CMS data using Webflow's Interactions.
• Include a close button and style as desired.

​

3. Add CMS Fields Using Custom Attributes or Embed

​

Webflow doesn't allow binding dynamic CMS content into a popup that's outside the Collection List by default. You can work around this by:

​

• Adding custom attributes (like data-name, data-description, etc.) to the popup trigger inside the Collection item.
• Alternatively, place hidden text elements inside each CMS item that store the extra info (e.g., description, image URL).

​

4. Use Webflow Interactions to Open and Populate Modal

​

• Add a Click interaction to the popup trigger element inside the CMS item.
• In the interaction:
• Set display: flex/block on the modal container.
• Use Element trigger animations (Interaction → Mouse click (tap)).
• To populate the modal:
• You need to use custom JavaScript because Webflow interactions alone can’t dynamically move CMS data into a separate modal. For example:
  • On popup trigger click, use JavaScript to fetch the data-* attributes from the clicked item.
  • Then inject those values into the modal content fields (e.g., modal title, body, image src).

​

5. Add a Close Interaction

​

• Add another interaction to the close button inside your modal to:
• Hide the modal container (set display: none).
• Optionally reset any fields or styles.

​

6. Optional – Use Finsweet Attributes (No-Code/Low-Code Option)

​

• If you want a no-code route, check Finsweet’s CMS Load and CMS Filter tools.
• You can dynamically display details in a modal using Finsweet Attributes with minimal code, and they offer documentation for creating dynamic modals from CMS items.

​

Summary

​

To open CMS Collection details in a popup instead of a new page, design a separate hidden modal on the same page, trigger it via a CMS-linked button using Webflow Interactions, and pass data from the clicked item using custom attributes or JavaScript.
