Data tree
The Data Tree Portlet can show a hierarchical structure of data and can be used in combination with other portlets to, for example, show data belonging to a specific node.
General
General data is required for all portlets.
Listeners
The portlet can listen to the following commands:
On Row Selection
On Filter
On Refresh
Data
Data source
The portlet data source configuration enables the portlet to execute specified queries towards the chosen database connector to fetch data, or fetch data from a workflow.
Database: uses a flow connector to retrieve data from a database
Workflow: runs a workflow to retrieve data
Nodes
Start value: the value that should be the starting node of the data tree
Nodes: column for the node id
Parents: the row parent value
Names: the name which will be displayed in data tree
Has Children: column with values "true" or "false" and indicated if the node has known children or not. A node where the row is set to false will not get an expand arrow.
Show root: tick the box if the root level is to be the first node.
This example data, configured as per the picture above, gives the data trees shown below as preview 1 and 2.
Click on node to select it, and click on the icon (or double click on node) to expand/collapse it. The child nodes will be loaded on expansion of the parent node.
Show root not ticked and HasChildren set in configuration.
Parent (marked in yellow) - visible when Show root ticked Arrow to expand (marked in red) - shown on all levels when HasChildren not set
Style
Change the header text color and add a header stripe by configuring style.
