The card explorer allows you to quickly find cards and add them to a tree.

• Cards which are already in the tree appear in the explorer grayed out.
• Cards not already in the tree appear colored by card type, and can be selected and dragged into the tree
• Up to 50 cards will be shown in the card explorer - you may need to restrict the list using filters as described below if the card you want is not displayed.

You can filter the cards that appear in the explorer by adding filter conditions in the Filter tab just as you do for the tree filter described above. In addition, you can use the Search tab to find cards matching any text.

To add cards to the tree

1. Center the tree view onto the card you want to use as the parent for the new cards. If the cards are of the top level type, then you should drop them onto the tree root

   

2. Select one or more cards in the explorer list

   • To select a single card, just left click on it anywhere and you can drag it.
   • To select multiple cards, check the box next to each card and then left click inside any one of them to drag the set.
   • You can use the Select All / None links to select all or none of the available cards in the list.
   

3. Drag the selected cards onto the tree view, and drop them on the chosen parent card.

   
   If you attempt to drop the new cards onto a card type which cannot act as a parent for all of the selected cards, Mingle will display an error message at the top of the page and the cards will not be added to the tree.
   

The newly added cards will have the relationship properties set to refer to their parent card in the tree, and any aggregate properties defined on that tree will be recalculated in the background.

You can add a card to a tree by selecting a parent card in the appropriate relationship property. The relationship properties for a tree are grouped in a named box in the card view.

Unlike other card properties, when you click on the relationship property, you are presented with a popup card selection widget showing all available parent cards. These parent cards are the cards of the appropriate type that are already in the tree, so if you don't see the one you're looking for - it may not yet have been added to the tree itself.

Click on the story you want and Mingle will return you to the card view.

In bulk edit mode you can change relationship properties, allowing you to add a number of cards to a single parent in a tree in one action.

You can create a card transition to assign a card into a tree by setting the corresponding relationship property.

You can specify a default value for a relationship property to automatically add a newly created card into a tree.
