In your web screens you can submit data, execute an action or navigate in your web flow. This behavior is implemented by the Button widget and the Link widget.
You can convert some widgets to links. How?
The Button widget and Link widget can be used in the following situations:
Submit the input: Each Web screen is mapped in a form, so when you use one of these widgets, you are submitting all the existing inputs.
Execute an action: Actions can be executed in the preparation of each screen and through a button or link.
Navigate in your Web flow: To navigate in your web flow you have to use buttons and links.
The Button widget and Link widget are very similar to the HTML elements: button and link (a href), respectively. The difference between these two widgets, besides their look and feel, is that in a Link widget you can decide whether to submit the input values or to navigate to another screen without submitting the input values, which is not possible with a Button.
