I can't drag-and-drop on my SMART Board, Chromebook, or touchscreen laptop when on Chrome. How do I fix this?

If you're not able to drag-and-drop when using Chrome on a SMART Board (or other interactive whiteboard) or touchscreen laptop, then you may need to enable Chrome's Touch Events API. Here's how: 

  • In Chrome, enter chrome://flags in the address bar.
  • Scroll down to the Touch Events API setting.
  • Select Enabled in the drop-down menu.
  • Restart Chrome.

UPDATE - January 2020

In previous versions of Chrome, "Touch Events API" could easily be turned on to allow for drag-and-drop in Vizzle. Since Chrome 78, this option is no longer available, though there is a temporary workaround. Here are the steps:

  1. In Chrome, press F12 (or Control+Shift+I) to open the developer tools
  2. Click the More Options button (looks like 3 vertical dots)
  3. Select More Tools > Sensors
  4. In the Sensors section on the bottom, scroll down to the Touch menu
  5. Select Force Enabled
  6. Refresh the tab and go to Vizzle NextGen

Please note, this workaround has to be turned on each time Vizzle NextGen is accessed. We are looking into a permanent solution for this.

For Windows 10, here's another workaround:

  1. Create a Chrome shortcut on the desktop (or anywhere else)
  2. Right-click your browser icon shortcut
  3. Click Properties
  4. Set the Target to: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --touch-events

    Yes! I had a teacher say she couldn't drag and drop in a game (in java) using her Smart Board while in Chrome. This fixed it! Your tip saved me hours of time. Thanks for posting!

    Chrome recently removed Touch Events API on v68. How do we do now?

    I researched Google's forums and it looks like a workaround is to force enable Touch in Chrome's developer tools. Here's how - https://groups.google.com/a/chromium.org/d/msg/chromium-discuss/43EvDVGan6E/MExSvi3FAgAJ
