Import

import { Iterate } from '@dnb/eufemia/extensions/forms'
render(<Iterate.EditContainer />)

Description

Iterate.EditContainer enables users to toggle (with animation) the content of each item between the Iterate.ViewContainer and this edit container. It can be used instead of the Iterate.AnimatedContainer.

By default, it features the Iterate.Toolbar containing a "Done" button and a "Cancel" button. The "Cancel" button resets any changes made to the item content, restoring it to its original state.

import { Iterate, Field, Value } from '@dnb/eufemia/extensions/forms'


render(
  <Iterate.Array>
    <Iterate.EditContainer
      title="Edit account holder"
      titleWhenNew="New account holder"
    >
      <Field.Name.Last itemPath="/name" />
    </Iterate.EditContainer>


    <Iterate.ViewContainer title="Account holder">
      <Value.Name.Last itemPath="/name" />
    </Iterate.ViewContainer>
  </Iterate.Array>,
)

The item number in the title

You can use the {itemNo} variable in the title or the titleWhenNew property to display the current item number.

import { Iterate, Field, Value } from '@dnb/eufemia/extensions/forms'


render(
  <Iterate.Array>
    <Iterate.EditContainer
      title="Edit account holder {itemNo}"
      titleWhenNew="New account holder {itemNo}"
    >
      <Field.Name.Last itemPath="/name" />
    </Iterate.EditContainer>
  </Iterate.Array>,
)

Get the internal item object

You can get the internal item object by using the Iterate.useItem hook.

import { Iterate, Field, Value } from '@dnb/eufemia/extensions/forms'


const MyItemForm = () => {
  // TypeScript type inference
  const item = Iterate.useItem<{ foo: string }>()
  console.log('My item:', item.index, item.value.foo)


  return <Field.String itemPath="/" />
}


render(
  <Iterate.Array value={['foo', 'bar']}>
    <MyItemForm />
  </Iterate.Array>,
)

Customize the Toolbar

import { Iterate, Field } from '@dnb/eufemia/extensions/forms'


render(
  <Iterate.Array>
    <Iterate.EditContainer>
      <Field.Name.Last itemPath="/name" />
      <Iterate.Toolbar>
        <Iterate.EditContainer.DoneButton />
        <Iterate.EditContainer.CancelButton />
      </Iterate.Toolbar>
    </Iterate.EditContainer>
  </Iterate.Array>,
)

Variants

minimumOneItem

This variant has the following behavior:

  • When EditContainer is visible, and the number of items in the array is one, the entire toolbar will be hidden.
import { Iterate } from '@dnb/eufemia/extensions/forms'


render(
  <Iterate.Array>
    <Iterate.EditContainer toolbarVariant="minimumOneItem">
      Item Content
    </Iterate.EditContainer>
  </Iterate.Array>,
)

Accessibility

The Iterate.EditContainer component has an aria-label attribute, which is set to the title property value. It uses a section element to wrap the content, which helps users with screen readers to get the needed announcement.

When the edit container becomes active, it will automatically receive the active element focus. And when the edit container switches to the view container, the focus will be set to the view container.
