Unable to add new collection to page

I have created a new page called Knowledgebase (it was duplicated) I have been able to remove the connection to the previous collection but can’t see how to connect to the Knowledgebase articles collection as on the page the padlock is still showing.

Hi Sharon,

You have to unbind all of the elements inside of your collection list first, before you can change the CMS collection it’s bound to. Look for the purple things. You may also have CMS-bound custom attributes, conditional visibility items etc that may not always be indicated in purple.

Thanks I will have a look at that.
