If you’re currently working on a Gutenberg block that includes a toggle control to hide or show content, and you’re facing issues with the editor not recognizing the changes made in the toggle control, don’t worry! In this guide, we’ll walk you through the steps to identify and fix this problem.

Understanding the Issue

The problem lies in the way your toggle control is interacting with the editor. While the toggle control updates correctly in the block component, the editor isn’t recognizing these changes. To resolve this, we need to ensure that the editor is aware of the updates made to the toggle control.

Solution: Update Block Attributes

To make the editor recognize the changes, you need to update a block attribute and use the setAttributes() function. This function informs the editor that a change has occurred and allows it to save the updated attribute.

Let’s go through the steps:

1. Add a New Attribute: In your block’s Edit function, declare a new attribute to store the state of the toggle control. In the provided code, the new attribute is named hideContent.

   
   const { blockcontent, hideContent } = attributes;
   

2. Update ToggleControl Component: Modify the ToggleControl component to use the newly added attribute and call setAttributes() to update its value.

   
   <ToggleControl
       label="Hide Content?"
       checked={hideContent}
       onChange={(checked) => {
           setAttributes({ hideContent: checked });
       }}
   />
   

3. Update Block.JSON: Ensure that you update your block’s block.json file to declare the new attribute. This step is crucial for the editor to recognize and save the changes.

   Example block.json snippet:

   
   {
       "attributes": {
           "blockcontent": {
               "type": "string"
           },
           "hideContent": {
               "type": "boolean",
               "default": false
           }
       },
       // ... other block configuration
   }
   

Testing and Troubleshooting

After making these changes, test your Gutenberg block in the editor. Toggle the control and check if the editor recognizes and saves the changes correctly. If any issues persist, double-check your code and ensure that the attribute updates are correctly implemented.
