Sometimes, work gets stuck due to dependencies, issues, or external factors. In these cases, you can block a card in Kanban Zone so your team is aware of the status and reason for the blockage.

Only licensed users (Administrators and Collaborators) can block or unblock cards.

Blocking a Card

1. Open the card you want to block.
2. Scroll to the Block section.
3. Type in your block reason.
4. Click Block.

Once blocked:

• The Block section header turns red.
• The reason becomes uneditable.
• You will see:
• • Blocked: shows the date, time, and user who blocked the card.
  • Last Edited: shows when and by whom the block was last updated.

How Blocked Cards Look on the Board

• A solid red banner appears across the card.
• The banner shows the block icon and the block reason.

Unblocking a Card

1. Open the blocked card.
2. Go to the Block section.
3. Click Unblock.

Once unblocked:

• The Blocked: field shows N/A.
• The Last Edited: field remains, showing when the block was last updated.

Advanced Blocking (Professional & Portfolio Plans Only)

With Advanced Blocking, you can categorize, track, and follow up on blockers in more detail.

Blocking a Card with Advanced Options

Follow the same steps as above, plus additional fields:

• Blocked Time – shows how long the card has been blocked.
• Type – pick a category (e.g., Legal, Vendor, Security) with its own color and icon.
• Severity – indicate seriousness (High, Medium, Low). Each severity can carry a reporting weight.
• Reminder Date – set a follow-up date. If the card stays blocked past this date, you’ll get an alert.

Customizing Advanced Blocking

Admins can configure these options in Organization Settings > Card Blocking.

There you can:

• Show/Hide Fields – decide which fields (Type, Severity, Reason, Reminder Date) appear on cards.
• Require Fields – make specific fields mandatory before a card can be blocked.
• Normal Block – disable all advanced fields to use a standard block.

How Advanced Blocks Look on the Board

• If a Type is chosen, the banner will use that type’s color and icon.
• The banner can also display:
• • Block reason
  • Severity
  • Reminder date
• If you don’t want these details shown, simply hide or unrequire the fields in settings.
