Empty heading & Icon as heading

Default template supports special column aliases to create column heading without content (empty) or with icon as heading content.

To use icon (font awesome) as heading for column in nested report use column alias DERIVIED<XX>_FA_<NAME> (e.g. ENAME as DERIVIED01_FA_USER) where

  • <XX> is 2 digit string eg. 01
  • <NAME> is icon class name with "_" instead of "-" eg. search

To create heading without content use DERIVIED<XX>_EMPTY (e.g. ENAME as DERIVIED01_EMPTY)

Manual events

Default callback supports 4 predefined actions (refresh, expand all, collapse, collapse all) that can be executed using anchors with proper classes. The table of clases can be viewed here. Actions works only when embeded in Extend default template or Custom template using Default Callback.

In the example, the first level of nested report uses Extend default template (preview embeded HTML) to embed 3 actions:

  • Expand all 2nd level nested reports defined with triggering element class ".showPersonal"
  • Collapse all expanded rows
  • Refresh itself

The 2nd level uses Custom template to render data (using custom mustache tamplete). Within template HTML are embeded 3 actions and one button supporting dialog page. Dialog close event is used to refresh nested report (preview custom template HTML).

  • Edit detailed data in modal APEX page and refresh nested report after closing modal. (close dialog dynamic action definition)
  • Collapse itself
  • Collapse itself with given time in anchor attribute duration
  • Refresh itself

Plugin event

Whenever the plugin shows, hides or refreshes nested report it triggers Default Callback [Pretius APEX Nested Reports] event. The event can be bound with dynamic actions on document (Selection Type set to Javascript Expression = document) to listen all nested reports events. Or the event can be bound to particular report (Selection Type set to Region) to listen only specific report events.

Event data describes state of currently active nested report. Event data object can be referenced by this.data within Execute JavaScript Code true Action. Event data object is described here.

Events example

In this example dynamic action bound with the plugin event changes looks of triggering element icon and add animaton. Javascript used in dynamic action "Execute Javascript Code" can be viewed here.

This example presents the plugin bound to HTML static table (not generated by APEX). The only difference is that the true action Affected Elements > Selection Type is set to jQuery Selector and Affected Elements > jQuery Selector is set to #staticHTMLTable.

You can inspect table HTML below the report.
