Buttons

Buttons are the Symphony elements responsible for submitting a form to the bot. As a result, all Symphony form elements are required to have at least one button where `type=action`. When an end-user clicks this button, the form and the value of each of the elements inside will be submitted to the bot via the datafeed and presented as a JSON payload.
In addition, some forms can contain reset buttons. These buttons are used to reset a form back to its original state.
Buttons support six different styles: primary, primary-link, secondary, tertiary, destructive and destructive-link. Each of those has different colors to suit different actions (to convey meaning). Use the class attribute to specify the style.
Primary: use the Primary button when there is a clear primary action on a message. You can use it for the submit button, for example.
Secondary: use the Secondary button when there are multiple actions of the same importance or some actions with less importance than a single primary action.
Destructive: use the Destructive button when an action results in the removal of an item or if it can result in a potentially serious negative consequence.
Primary-link, Tertiary and Destructive-link: These styles are variations respectively of the Primary, Secondary and Destructive buttons but without borders. They are low prominence options that can be used alongside a Primary or as standalone buttons with the ability to read more information.
Attributes
Attribute
Type
Required?
Description
name
String
Yes
Identifies the clicked button.
type
String
No

If type is not specified, the default value will be type=”action”
Indicates whether the button is an action button or a reset button. When clicked, the action button sends the form information to the datafeed. On the other hand, the reset button resets the form-data to its initial values.

Accepted values: action and reset.
class
String
No
Toggle between new palette of colors: primary, secondary, destructive, primary-link, tertiary and destructive-link.  
data-icon
String
No
Adds an icon before the button name. Only icons from our UI Toolkit list are supported. Each icon is identified by its name.
Rules and Limitations
If class is not defined, the action button assumes the primary class by default. Action buttons should be used for affirmation or confirmation actions.
Reset buttons have the secondary class set by default. Reset buttons should be used when the content of the fields need to return to their original state.
Examples
The following example shows the use of the Reset and the Submit button when sending a text inserted in a Text Field.
