..If you try to integrate fullPage.js with Webflow Editor CMS, you'll soon realize that the scroll is blocked and there seems to be a compatibility issue between both. 

You won't be able to update the collections and use the CMS interface.

You can use this code in order to fix the conflict between the Webflo Editor CMS and fullpage.js:

Webflow.push(function () {

  // check is the CMS editor is there
  if (Webflow.env('editor') != undefined) {

    // Your current fullPage.js initialisation should be here
    new fullpage('#fullpage', {
       licenseKey: 'YOUR_LICENSE_KEY_HERE'
       // more options here

This issue was first discussed on the fullPage.js forum but has also been treated on the Webflow forum:
