Concepts

Wizard structure

A wizard contains steps which contain sections which contain inputs.

import { WizardPage, Step, Section, TextInput, Select } from '@patternfly-labs/react-form-wizard'

function Example() {
   return (
      <WizardPage title="My Wizard">
         <Step label="Details" id="details-step">
            <Section label="Details">
               <TextInput label="Name" path="name" required />
               <Select label="Namespace" path="namespace" options={['default', 'namespace-1']} />
            </Section>
         </Step>
      </WizardPage>
   )
}

Item Context

The wizard works by setting an item context which inputs use as a data source. Inputs then get value or set value in the item context using path notation.

function Example() {
   return (
      <TextInput label="Name" path="metadata.name" required />
   )
}

Some inputs can change the item context, such as the ArrayInput.

function Example() {
   return (
      <ArrayInput path="resources" placeholder="Add new resource">
         <TextInput label="Name" path="metadata.name" required />
         <Select label="Namespace" path="metadata.namespace" options={['default']} required/>
      </ArrayInput>
   )
}

Working with an array of items

The root data can either be an object or an array of objects. When working with an array of objects anItemSelector can be used to set the item context specific item.

function Example() {
   return (
      <ItemSelector selectKey="kind" selectValue="Application">
         <TextInput label="Name" path="metadata.name" required />
         <Select label="Namespace" path="metadata.namespace" options={['default']} required/>
      </ItemSelector>
   )
}

ArrayInput can also be used to work with a subset of items in this case.

function Example() {
   return (
      <ArrayInput path={null} filter={(item) => item.kind === 'Subscription'}>
         <TextInput label="Name" path="metadata.name" required />
         <Select label="Namespace" path="metadata.namespace" options={['default']} required/>
      </ArrayInput>
   )
}

Input common properties

• label - The label for the input.
• path - The path the input is getting and setting value to, in the current item context.
• id - Optional id of the input control. Used for testing. If not set, defaults to a sanitized version of the path.
• validation - Optional validation function that takes in the current item context and input value. It should return an error string if there is an error.
• hidden - Optional hidden function that takes in the current item context and returns true if the input should be hidden.

Validation

Inputs take an optional validation function. The validation function takes in the current item context and input value. It should returns a validation error string if the validation fails.

Conditional hiding

Inputs take an optional hidden function. The hidden function takes in the current item context, and returns true if the input should be hidden.

Steps and Sections automatically hide if all its inputs are hidden. This makes it easy to make a wizard with conditional flow.

Examples
