JET FormLayout Component

Description: The oj-c-form-layout component provides a responsive layout capability to lay out child elements in the row or column direction where the number of columns displayed depends on the available width of the container. Child components are responsible for rendering the label with the alignment as specified by the oj-c-form-layout's label-edge property, which the child components consume.

<oj-c-form-layout columns="2">
  <oj-c-input-text label-hint="First Name"></oj-c-input-text>
  <oj-c-input-text label-hint="Last Name"></oj-c-input-text>
  <oj-c-input-text label-hint="address" column-span="2"></oj-c-input-text>
</oj-c-form-layout>


Usage

Signature:

interface CFormLayoutElement

Typescript Import Format
//To typecheck the element APIs, import as below.
import { CFormLayoutElement } from "oj-c/form-layout";

//For the transpiled javascript to load the element's module, import as below
import "oj-c/form-layout";

Note: Application logic should not interact with the component's properties or invoke its methods until the BusyContext indicates that the component is ready for interaction.


Slots

JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.

Default

The default slot is the content of the form layout. The oj-c-form-layout element expects core pack form component children for the default slot.
