Using the Dropbox Power-Up
Enabling the Power-Up
To enable the Power-Up, open the board menu on the right side of the page, select the Power-Ups menu option, and then click the "enable" button next to the Dropbox Power-Up.
Alternatively, you can enable the Dropbox Power-Up from a Trello card if you have a Dropbox file attached to the card.
Authenticating with Dropbox
Once the Power-Up is enabled for the board, each individual user will need to authenticate their Dropbox account from within Trello. To do that, open up a card, click the Dropbox button in the Power-Ups section on the back of the board, and select "Attach a file" or "Attach a folder."
A popup window will open. Click "sign-in" and log in with your username and password.
Using the Power-Up
You can access the Power-Up from the back of the card by clicking the Dropbox button in the Power-Up section. Select “Choose a file or folder.”
You will be given the option to navigate through your Dropbox folders and select the file or folder you want to attach. Attachments will appear under the Dropbox files or Dropbox folders header on the card.
With the power-up, you can see rich thumbnails of attachments under the Dropbox Files section. If you’re unable to view the thumbnail, it means your Dropbox account doesn’t have permission to access the attachment. Make sure you are logged in to the correct Dropbox account in your browser.
You can also create a shareable Dropbox link by hovering over the thumbnail and clicking on the link icon. This will copy the link to your clipboard.
Clicking on the thumbnail will open a Dropbox preview of the file. From the preview, you can share the file, view the activity on the file, or open the file in a native application.
Removing files and folders
To remove a file, select “Remove…” next to the Dropbox Files header. To remove a folder, select “Remove…” next to the Dropbox folders header.
If there is only one Dropbox attachment, you can directly select “Remove.” If there are multiple Dropbox attachments, select the file or folder you want to remove from the list, then select “Remove.”
Disabling the Power-Up
To disable the authorization with your Dropbox account, open the Power-Ups menu on the right side of the board. Then, click “Settings” and select "Disable".
Alternatively, you can disable the Power-Up from the sidebar menu. Click on Dropbox to view your options. Click ‘Disable’ to disable the Power-Up.
Disabling the Power-Up will not cause any data loss. It will change the formatting of the links in the card to be the same as any other attached links (just like how non-Business Class users would see the links on the card when the Power-Up is enabled)
