To prevent all items in a Webflow collection from getting updated when selecting a PDF or URL for a specific item, you can follow these steps:
1. Create a new field for the specific item in your Webflow collection. For example, you can name it "Attachment" or "File."
2. Set the field type as a file upload or a URL field, depending on your requirements. If you want to allow users to upload PDF files, use the file upload field type. If you want to add URLs, use the URL field type.
3. Now, go to your collection list template or collection page template where you want to display the items.
4. Drag and drop a text or link block element to the desired location on the template.
5. Connect the text or link block element to the "Attachment" or "File" field of the collection item.
6. Customize the design and add any necessary interactions to enhance the user experience.
By setting the specific item as a separate field within the collection, you isolate that element and prevent it from impacting other items or triggering updates to the entire collection whenever it is modified.
With this setup, each item will have its own separate field for the file upload or URL, and you can individually control and update the specific items without affecting the rest of the collection.
