How to Change Block Arguments in Magento 2

In this post, I’m going to guide you on how to change block arguments in Magento 2.

How to Change Block Arguments

For the block arguments to be modified, the <referenceBlock> instruction is used.

Below is an example of how to change the existing block argument’s value and also add a new argument.

• Initial block declaration:

<block class="Namespace_Module_Block_Type" name="block.example">
  <arguments>
    <argument name="label" xsi:type="string">Block Label</argument>
  </arguments>
</block>

• Extending layout:

<referenceBlock name="block.example">
  <arguments>
    <!-- Modified block argument -->
    <argument name="label" xsi:type="string">New Block Label</argument>
    <!- Newly added block argument -->
    <argument name="custom_label" xsi:type="string">Custom Block Label</argument>
  </arguments>
</referenceBlock>
