Question

I want to show color swatches of configurable product in home page But My all static blocks in cms page. Here is my static block

{{block class="Smartwave\Filterproducts\Block\Home\LatestList" name="latest" aspect_ratio="1" column_count="6" product_count="12" image_width="212" product_type="3" template="grid.phtml"}}

Here is my layout xml code which is working fine to display color swatches in home page but I want to show convert body part in static block. Should I use addchild() method in LatestList block file ? If yes how ?

<?xml version="1.0"?>

                <block class="Magento\Swatches\Block\Product\Renderer\Listing\Configurable" as="configurable" template="Magento_Swatches::product/listing/renderer.phtml" />
        </referenceBlock>     

        <referenceContainer name="main">
          <container name="topproduct" htmlTag="div" htmlClass="topproduct">

                      </block>
                  </block>
           </container>
        </referenceContainer>
    </body>
</page>

Solution

The below does render some product swatches for the product in the listing.

     <?php

namespace Mbs\HomeProducts\Block;

use Magento\Swatches\Block\Product\Renderer\Configurable;

class LatestList extends \Magento\Catalog\Block\Product\ListProduct
{
    public function getCategoryId()
    {
        return 12;
    }

    /**
     * <block class="Magento\Framework\View\Element\RendererList" name="category.product.type.details.renderers" as="details.renderers">
    <block class="Magento\Framework\View\Element\Template" name="category.product.type.details.renderers.default" as="default"/>
    <block class="Magento\Swatches\Block\Product\Renderer\Listing\Configurable" name="category.product.type.details.renderers.configurable" as="configurable" template="Magento_Swatches::product/listing/renderer.phtml" ifconfig="catalog/frontend/show_swatches_in_product_list" />
    </block>
     *
     * @return LatestList|void
     * @throws \Magento\Framework\Exception\LocalizedExceptioN
     */
    protected function _prepareLayout()
    {
        $this->addChild(
            'details.renderers',
            \Magento\Framework\View\Element\RendererList::class
        );

        $this->getLayout()->getBlock($this->getNameInLayout() . '.details.renderers')
            ->addChild('default', \Magento\Framework\View\Element\Template::class);

        $configurableRenderer = $this->getLayout()->getBlock($this->getNameInLayout() . '.details.renderers')
            ->addChild('configurable', \Magento\Swatches\Block\Product\Renderer\Listing\Configurable::class);
        $configurableRenderer->setTemplate('Magento_Swatches::product/listing/renderer.phtml');

        parent::_prepareLayout();
    }
}
