How to create sub-tasks in trello

Caz Wright

I have a list of tasks, but need to link one task to another in the sense that one task can only be done after the other has been completed.

For example: Task A and Task B are both listed, but Task B can only be done when Task A is complete. How do I link these two tasks together, or how do I create Task B as a sub-task of Task A?

@Caz Wright welcome to the community! you can use the checklist feature to add subtasks inside a trello card. You can also make those subtasks be other trello cards too. If you're using Trello Standard or higher, you can add due dates and owners to those sub task, and you can drag them around to reorder them, which is one way i kinda think through dependencies. 

There are also power-ups like Hello Epics that handle dependencies and parent child relationships with cards, which you might find helpful too!
