The links between the cards can be created, modified, and deleted from the planning. Only cards of the same type can be linked (Project-Project, Phase-Phase, etc.).
The links between cards in the planning are only “Finish-Start” links. When adding a link, the two cards will then be connected end-to-end by reducing the margin between these 2 cards to 0 days.
Place the mouse on a card, two circles appear at the ends of the card. Click on one of the circles and pull the link to another form.
Click on the link to delete it. A confirmation window will appear where the user can validate or not the deletion.
