11. Configurable Release Block – Volto Hands-On

Configurable Release Block

11. Configurable Release Block#

The next Block we will . We will use this to learn how to create a Block that is configurable by an editor.

11.1. Initital Block setups#

The initial setup for this Block is the same as for the slider Block. Create a new folder in src/components/Blocks called release and in there View.jsx as well as Edit.jsx. For now give them the same initial content as we did with the slider:

import React from 'react';

const View = (props) => {
  return <div>I'm the Release view component!</div>;
};

export default View;

And for Edit.jsx correspondingly. Export the blocks via the index.js and register the block in config.js like you did with the slider. Now you can add it to your page. You can use the same SVG as for the release but you can also pick something of you choice from pastanaga ui. All the icons there are available in Volto by default.

11.2. Create the schema for your Block#

First you have to identify what fields the Block needs an editor to be able to edit and of what type. In our case those will be the following:

  • title: The field that contains "Get the latest Plone" in the original

  • description/subtitle: The text underneath the title

  • buttontext: text displayed on the red button

  • buttonlink: where the button should link to

  • image: Logo of current Plone release

To define these fields we will create a schema inside the new file schema.js within the release folder. Then paste the following into schema.js:

export const schemaRelease = (props) => {
  return {
    required: [],
    fieldsets: [
      {
        id: 'default',
        title: 'Default',
        fields: ['title', 'description', 'image', 'imageAlt'],
      },
      {
        id: 'button',
        title: 'Button',
        fields: ['buttonTitle', 'buttonLink'],
      },
    ],
    properties: {
      title: {
        title: 'Title',
        widget: 'text',
      },
      description: {
        title: 'Description',
        widget: 'text',
      },
      buttonTitle: {
        title: 'Button Title',
        widget: 'text',
      },
      buttonLink: {
        title: 'Button link',
        widget: 'object_browser',
        mode: 'link',
        allowExternals: true,
      },
      image: {
        title: 'Image',
        widget: 'object_browser',
        mode: 'image',
      },
      imageAlt: {
        title: 'Image alt text',
        widget: 'text',
      },
    },
  };
};

export default schemaRelease;

The properties key will contain all the fields, while the fieldsets key assignes the fields to different fieldsets. In the required array you can define certain fields as required. If you have already experience in working with classic Plone, you will notice, that this is very similar to how you would create content types there.

11.3. Implement schema in sidebar#

To implement the schema in the sidebar of your block you will have to create another component called Data.jsx in which the schema will be transformed to proper react inputs. Paste the following into the Data.jsx file:

import { BlockDataForm } from '@plone/volto/components';
import Schema from './schema';

const ReleaseData = (props) => {
  const { data, block, onChangeBlock, blocksConfig } = props;
  const schema = Schema({ ...props });
  return (
    <BlockDataForm
      schema={schema}
      title={schema.title}
      onChangeField={(id, value) => {
        onChangeBlock(block, {
          ...data,
          [id]: value,
        });
      }}
      onChangeBlock={onChangeBlock}
      formData={data}
      block={block}
      blocksConfig={blocksConfig}
    />
  );
};

export default ReleaseData;

The BlockDataForm component will transform the schema.js data into a usable sidebar. You now can add that sidebar to your Blocks Last but not least you need to amend Edit.jsx to use that sidebar:

import { SidebarPortal } from '@plone/volto/components';
import { withBlockExtensions } from '@plone/volto/helpers';
import ReleaseData from './Data';
import View from './View';

const Edit = (props) => {
  const { data, onChangeBlock, block, selected } = props;
  return (
    <>
      <View {...props} />
      <SidebarPortal selected={selected}>
        <ReleaseData
          key={block}
          {...props}
          data={data}
          block={block}
          onChangeBlock={onChangeBlock}
        />
      </SidebarPortal>
    </>
  );
};

export default withBlockExtensions(Edit);

11.4. Create the View#

You are now able to edit the content of your Block, but will still see your default "This is the View" text. To change that amend View.jsx as follows:

import { Container } from 'semantic-ui-react';
import { UniversalLink } from '@plone/volto/components';

const ReleaseView = (props) => {
  const { data } = props;
  return (
    <div className="block release full-width">
      <Container>
        <h2>{data.title}</h2>
        <div className="text-button-wrapper">
          <p>{data.description}</p>
          {data.buttonLink && (
            <UniversalLink
              className="button-link"
              href={data.buttonLink[0]['@id']}
              openInNewTab
            >
              {data.buttonTitle}
            </UniversalLink>
          )}
        </div>
        {data.image.length > 0 && (
          <img
            src={`${data.image[0]['@id']}/@@images/image`}
            alt={data.imageAlt}
          />
        )}
      </Container>
    </div>
  );
};

export default ReleaseView;

Note that all the fields defined in the schema and filled via the sidebar can now be accessed from the data key of the blocks props. You can use console.log(data) to see the details.

To make the block look like its twin on https://plone.org, we only need to add the following CSS to our custom.overrides:

// Release block
.block.release {
  background: #f0f8fc;
  padding: 20px 0;
  h2 {
    font-weight: bold;
  }
  .text-button-wrapper {
    display: flex;
    justify-content: space-between;

    p {
      width: 600px;
      font-size: 1.25rem;
      color: #595959;
      font-weight: 300;
    }

    a {
      border-radius: 0;
      color: @white;
      background: @blue;
      border: 2px solid @blue;
      font-weight: normal;
      padding: 14px 20px 16px 22px;
      display: inline-block;
      line-height: 1em;
      height: 56px;
      margin-right: 150px;
      &::after {
        background-image: url(https://plone.org/static/media/arrow-right-white.141ecd63.svg);
        display: inline-block;
        width: 22px;
        height: 22px;
        margin-left: 1.5em;
        background-repeat: no-repeat;
        background-size: cover;
        content: '';
        vertical-align: text-top;
      }

      &:hover {
        background: @white;
        color: @blue;

        &::after {
          background-image: url(https://plone.org/static/media/arrow-right.c1b96a21.svg);
        }
      }
    }
  }
}

11.5. Release#

When done, you can enter edit mode on your frontpage and add the respective text as on the original plone.org.

For the image create a new Image-type Plone content object and upload the Plone 6 image from the training ressources. Then Choose that Image in the edit toolbar of your Block.
