About tree tables
A tree table combines a tree or hierarchical structure with a table so that you can expand and collapse nodes and display multiple columns of data for each node in the tree.
In z/OSMF, tree tables have expand (+) and collapse (-) icons in a column in the table data area of the table. Click these icons to show or hide the child nodes. For more details, see help topic Expanding and collapsing nodes.
The row that contains the child nodes is referred to as the parent node. A child node can also be a parent if it contains other nodes.
Table views
Some tree tables have a non-tree view. In the table toolbar for those tables, Table view: Tree is displayed. To switch to the non-tree view, complete the steps provided in help topic Switching between table views. For an overview of the differences between the two views, see Table 1.
| Action | Tree View | Non-Tree View |
|---|---|---|
| Selecting and deselecting nodes | In multi-select tree tables, a relationship
exists between the selection and deselection of child and parent nodes.
For example, selecting or deselecting a parent node causes the corresponding
child nodes to also be selected or deselected. In single-select tree tables, you can select only one child or parent node; therefore, there is no relationship between the selection or deselection of nodes. |
No relationship exists between the selection and deselection of child and parent nodes. For example, selecting or deselecting a parent node does not select or deselect the corresponding child nodes. |
| Expanding and collapsing nodes | You can expand and collapse nodes. | You cannot expand and collapse nodes. |
| Sorting nodes | Sort and preserve the parent-child relationship. | Sort and ignore the parent-child relationship. Similar to sorting in standard tables. |
| Filtering nodes | Filter and preserve the parent-child relationship. | Filter and ignore the parent-child relationship. Similar to filtering in standard tables. |
