How to Design with SAIL

Overview

All components are backed by expressions. This means you have two ways of working with components to design interfaces.

• Design Mode - Simply drag and drop components onto a canvas, then configure them in the configuration pane.
• Expression Mode - Switch over to expression mode to add more advanced functionality, such as data integrations and conditional logic.

This page provides a short summary of what this looks like in practice.

Working with components and expressions

Here is a simple text field.

The expression to create this field looks like this:

1
2
3
a!textField(
    label: "Street Address"
  )

If you want to make changes to the text field, simply update the available parameters in the COMPONENT CONFIGURATION pane.

The expression automatically updates with the new parameters.

a!textField(
  label: "Street Address",
  instructions: "Enter a street address",
  helpTooltip: "Do not include the city or state",
  placeholder: "123 Main St."
)

Working with data

It isn't very useful to just hard code data into a user input field. That's why SAIL allows you to easily associate the value of a field with application data. For example, you can use local variables to map application data to the text field.

a!textField(
  label: "Street Address",
  instructions: "Enter a street address",
  helpTooltip: "Do not include the city or state",
  placeholder: "123 Main St.",
!  value: local!streetAddress,
!  saveInto: local!streetAddress
)

Working with logic

You can also add dynamic logic to your interfaces. For example, you can use the showWhen parameter to only show the address field when a certain condition is true.

  instructions: "Enter a street address",
  helpTooltip: "Do not include the city or state",
  placeholder: "123 Main St.",
  value: local!streetAddress,
  saveInto: local!streetAddress,
!  showWhen: local!showAddressField=true
)
