Outcome Button Group

Outcome Button Group is a specialized version of Button Group, typically used in user task forms. The Outcome Button Group has two main differences:

1. The buttons will be rendered as outcomes of the form.
2. When an outcome button is clicked, the form is submitted.

Properties

General

Attribute	Type	Description	Category
Model Id	String	This is a unique id for the component.	Every field on a form model needs a unique ID, which is automatically generated but can be changed if needed (e.g. to reference in expressions or for debugging purposes). If the field type supports rendering a label, and most types do, it can be configured here. This label is a displayed on the form to the end user and typically indicates what value is expected in the field. The documentation property holds free-form text that can be used to give more details about this outcome button group, like its purpose, usage in other models, etc.
Label	Text	The label attribute adds a label to the component.
Label position	Selection: Left Top	The position of the label, you can choose between left or top.
Label tooltip	Text	When it is defined, a question mark icon will appear in the component label. When the user hovers over it it will show this text in a tooltip.
Documentation	Multiline Text	A free-form text to explain the use cases for this form field.
Button align	Selection: Left Center Right	Button align.	Configure where the button(s) will be displayed and whether they should be kept in-sight or not.
Show as split button	Boolean	A single button will be rendered, when clicked by the user, the buttons added here will appear
Show label	Boolean	Use the button group label when rendered as a dropdown.
Keep in form	Boolean	Prevent this outcome button group to be rendered in the header, and render it in its place in the form.

Validation

Attribute	Type	Description	Category
Validation Panel Display	Selection: Show Only message Hide	Display at validation panel and validation tooltip.	Providing proper data in form fields is important, especially when in process, case, decision or any other models the values provided in the form fields are used in subsequent steps. To make sure that the data is correct, validation is crucial. For this reason, a form can only be submitted when all fields are valid and thus all validation properties configured on the left apply. Check the tooltips on the properties for more information.
Custom validations	List	List of additional validations to apply.	The outcome button group can have custom validation rules beyond the standard set of validations. Such a rule is written as a frontend expression in the form of {{myExpression}}. If this expression evaluates to false, the submission of the form won't be possible.

Rendering

Attribute	Type	Description	Category
Description	Text	The description attribute adds a description to the component.	Some field types have an extra line of text displayed to give the user more details about the field.
Ignored	Boolean	If true the component will be hidden and the value will not be part of any payload.	Fields can also be shown or hidden based on the visible condition. This can be a frontend expression in the form of {{myExpression}} which can reference other form field values by their IDs. Fields can also be enabled or disabled, and similarly this can be made dynamic based on a frontend expression. Some field types can be ignored (the property is shown here if that's the case), which means that its value won't be taken into account.
Visible	Boolean	Boolean value or expression specifies whether the component is visible or hidden. This expression might include another value in the same form, for instance use a checkbox bound to {{showAdditionalFields}} and use the very same expression as the visible attribute to show or hide the component according the checked state of the checkbox. If you want to only show the component, if the form is not used as the init-form, you can use the expression '{{root.id}}' which evaluates to true only, if there is a current case id which is not the case in an initialization form.
Enabled	Boolean	Boolean value or expression specifies whether component is enabled or disabled.
Style class	Text	Stylesheet class name. Add any style classes to be applied to the component for the desired styling and rendering.	The outcome button group can get customized CSS classes to customize the default styling. Note that the CSS files needed for the customizations must be available on the runtime system.

Advanced

Attribute	Type	Description	Category
Events	List		The outcome button group emits low-level events on which can be reacted with a frontend expression to implement various use cases that are not possible with regular modeling. If the expression produces a value, it can be stored in a new variable using the Result variable property.
