Custom rule development
There are currently 60 predefined rules available to use in forms and processes, across 10 categories:
Click on the relevant links to find out more about each area. However if customised rules have been created, they are available to those with the role Administration and Design business process to use in process and form design in Kianda Designer. Customised rules are available under the Custom rules category under Add a rule.
Custom rules are created by Administrators or Developers who have coding experience to use Kianda’s low-code development feature, Kianda Developer.
How to get started
If you are an experienced developer with an Administrator or Developer role, see Users & Groups, you can create a new rule widget within Kianda by doing the following:
Navigate to Administration in the left-hand side menu, and click on Developer. This will bring you to the Developer resources page. Rule widgets are of type ‘Rule’ in this list.
Click on New widget to create a new rule widget.
Fill out the Edit widget dialog box - that is Title, Unique Id (which is autofilled from the title), Widget Icon, where you can select from hundreds of icons, and then Widget type.
Click on OK when complete.
When you create a custom field widget, the Widget UI and Widget Code tabs are displayed. These two screenshots show the default code for ‘Widget UI’ and ‘Widget Code’.
The ‘Widget UI’ defines the HTML, handlers, expressions and more.
Rule widget UI
The ‘Widget Code’ defines the logic and functions.
Rule widget code
Widgets created are visible in the main widget view. From here, you can edit a widget by clicking on the Edit button (Pen icon), delete a widget by clicking on the Bin/Trash button and restore earlier versions of a widget by clicking on the Version restore button .
Custom rule widgets you create will be available for use in Kianda Designer by going to Side menu > Administration > Designer > click on an existing process or Add new to add a new process, then click on Add a rule to see the Custom rule category added under Rules.
To continue with low-code development, you can view Templating basics. If you would like to learn more about low-code go to the Low-code development page and from there navigate to other pages on low-code practices.
