Assign cards to milestones
There are three ways to assign cards to milestones:
1. If you only want to update one card, the easiest thing to do is to set the milestone attribute on the right-hand panel when you click on the card.
2. If you want to assign multiple cards to milestones, you can also set the layout of your board to list the cards by milestone, and then simply assign them by drag and drop.
3. On the Gantt view, you can also assign cards to milestones by dragging the order of the card to a milestone.
You can change the order of milestones by changing the order in the Gantt chart, you can do this by dragging a milestone to its new position. This is shown in the screen recording below.
You can delete a milestone from the board detail pop-up, you can access the detail pop-up from the overview tab or by clicking on the board title. Go to the milestone tab to delete a milestone.
You can also add or re-order milestones from this pop-up.
