How can I resolve the issue with my pop up modals in Webflow's CMS Collection, where the modals are not displaying the correct information and closing one modal triggers others with the same class?

When using pop-up modals in a Webflow CMS Collection List, the issue typically stems from shared classes and IDs, causing every modal to open or close together instead of independently.

1. Understand the Core Problem

• Webflow reuses classes and interactions across Collection items, which means if you apply the same modal structure and ID across CMS items, they behave identically.
• Multiple elements inside a Collection List cannot have the same ID, and interactions based on class names will apply to all elements with that class unless scoped properly.

2. Use a Unique Structure per Modal

• Avoid using IDs inside a CMS Collection List, as IDs must be unique across the entire page. Instead, use classes and dynamic data attributes.
• Use Webflow’s built-in “Current” targeting logic if applicable — for example, to style or show content relative to the current Collection item.

3. Scope Your Interactions

• In Webflow Interactions (IX2), when assigning a trigger (like a button to open a modal), do the following:
• Set the trigger to affect a Sibling or Child element only.
• Under "Affect", select Only children of this element or Only siblings with this class, depending on your layout.
• This keeps the interaction scoped to only the current Collection item.

4. Use CMS Bindings for Dynamic Content

• Bind dynamic content (e.g., title, description, image) from the CMS directly inside each modal, so each modal reflects its correct data.
• Make sure all modal content fields are placed within the Collection Item in the Webflow Designer.

5. Prevent Multiple Modals from Closing Together

• If your close interaction targets a class that’s shared across all items, it will close all modals.
• Instead, as with the open interaction, scope the close interaction to affect only the modal related to the active item:
• Choose the “Only siblings with this class” option when defining the element to hide.
• Verify that both the open and close interactions are scoped to within the same Collection Item.

6. Test & Preview Per Item

• Use Webflow’s Preview mode to test if clicking each trigger only opens its respective modal.
• If closing one modal still closes others, double-check the interaction scopes and element hierarchy in the Designer navigator.

Summary

To fix CMS modals showing incorrect info or all closing/opening at once, scope your interactions to only target elements within each Collection Item, avoid duplicate IDs, and use CMS bindings for dynamic content. Always test in Preview to confirm independent behavior.
