Hierarchy Navigation

When using a tree slide there are a number of options available to adjust the view of the hierarchy being shown and to edit the nodes displayed

These can be accessed either via the Tree slide toolbar or the Right Click Menu

Right Click Menu

Right-clicking on the canvas in a Tree slide will present a menu with a number of options:

image

  1. Edit Node
  2. Orphan Node
  3. Create Node
  4. Clone Node
  5. Delete Node
  6. Zoom Controls
  7. Focus
  8. Clear Focus
  9. Clear Selection
  10. Expand Next-Collapse Last
  11. Expand All-Collapse All
  12. Parent by

In addition to the options on the menu it is possible to:

Tree slide toolbar

Selecting a node on a tree slide will display a toolbar on the canvas which brings together a number of functions for interacting with nodes

Each of these functions can also be accessed via other methods

  1. Pin toolbar
  2. Focus
  3. Clear Focus
  4. Expand Next
  5. Collapse Last
  6. Create Node
  7. Clone Node
  8. Edit Node
  9. Orphan Node
  10. Revert Changes
  11. Delete Node

Pin Toolbar

The pin toolbar function is available on the Tree Slide Toolbar and selecting it will retain the toolbar position on the canvas regardless of other nodes being selected

Once pinned the tool bar may be moved around the canvas using the 6 dots to grab and drag the tool bar to the desired location

Toolbar Drop Zones

With the toolbar pinned each of the buttons on the toolbar are available as drop zone targets to drag node(s) onto

Dragging node(s) onto a drop zone will activate the relevant action

Zoom Controls

  • A. These controls allow you to zoom in and out on a tree and scale the tree to fit on the screen
  • B. These controls are also repeated in the bottom right of the screen
  • C. The 0 / + / - keys on the top row of the keyboard are also shortcuts for these functions

Focus

The focus function allows you to select a node and make that node the focus, or root, of your displayed tree

Selecting any node(s) and then clicking on Focus will set the tree to show the node(s) as the root of the displayed tree

Note: focusing on a node, or collection of nodes acts as global filter across the whole pack. Focus can be cleared from any Tree slide via the Clear Focus action

Focus on a Single Node

To focus on a single node:

Either

image

  1. Select the required node
  2. Right Click to open menu
  3. Select focus

Or

image

  1. Select the required node
  2. Select the focus button on the Tree slide toolbar

Dragging a node to Focus on the Data Node Summary or double-clicking on a node in the tree will also Focus on that node

Focus on Multiple Nodes

You can focus on multiple nodes at the same time. This allows you to view several trees side by side in the same view

This can be especially useful when the nodes you wish to view are at different levels of the hierarchy

To focus on multiple nodes:

image

  1. Use one of the methods covered in the section Select Multiple Nodes to select the nodes to be focused on
  2. Right-click on the canvas to open the menu
  3. Select Focus

image

  1. The selected nodes will then be shown side by side as the root of their respective trees

Clear Focus

This option on the menu resets the tree slide to show original view of hierarchy

It is possible to clear the focused nodes by selecting the X shown in the footer when hovering over the focused nodes summary

image

Or by using the Clear Focus button on the Tree slide toolbar

image

Clear Selection

This option on the menu deselects all nodes

Just like Clear Focus this can also be done by selecting the X shown in the footer when hovering over the selected nodes summary

image

Expand Next Collapse Last

Note: These options will only work once one or more nodes have been selected and will apply the action to all selected nodes

  1. Select node(s)
  2. Right click to open menu
  3. Select either:
    • Expand visible tree by 1 level
    • Collapse tree by one level
  4. The level below selected node(s) will be shown

The Expand Next & Collapse Last buttons on the Tree Slide Toolbar provide the same functionality as the Right Click Menu

It is also possible to use the keyboard shortcut of CTRL + Down Arrow and CTRL + Up Arrow to perform the same actions on a selected node

image

Expand All Collapse All

Note: These options will only work once one or more nodes have been selected and will apply the action to all selected nodes

This option works similarly as expand and collapse next level, but it expands and collapses all available levels below the selected node(s)

This is demonstrated here
