Editing a Tree as a Developer

Accessing the Tree Attributes Page

Developers can customize a tree by editing attributes on the Tree Attributes page.

To access the Tree Attributes page:

1. Navigate to the appropriate Page Definition. See "Accessing the Page Definition".

2. Access the Tree Attributes page:

   • Tree view - Right-click on the Region name and select Edit Tree.

   • Component View - Under Regions, click the Tree link next to the name of the tree region you want to edit.

   The Tree Attributes page appears and is divided into the following sections:

   • Display Settings enable you control a tree's appearance and functionality. Use these settings to define a tree template, tooltip, a page item to hold the last selected node value for saving tree state, determine whether the tree has focus on page load, and what action activates node links on a tree.

   • Query enables you to edit the SQL query underlying the tree. The query must be in the following format:

     SELECT status, level, name, icon, id, tooltip, link 
     FROM ... 
     WHERE ... 
     START WITH... 
     CONNECT BY PRIOR id = pid 
     
     ORDER SIBLINGS BY ...
     

3. To learn more about a specific attribute, click the item label.

   When Help is available, the item label changes to red when you pass your cursor over it and the cursor changes to an arrow and question mark. See "About Field-Level Help".

4. Click Apply Changes.
