I would like to remove the heading option from the RTE tool by App Builder.

[太郎榊原1]

I am currently customizing the Rich Text Editor (RTE) using App Builder.

I am implementing it according to the documentation, but even after inputting the ID for the h1, it is not being removed from the tool.

rte: {
  removeButtons: () => [
    {
      id: "h1",// not work
    },
    {
      id: "bold", //work
    }
  ],
}

 Could the ID be incorrect? I would appreciate it if you could share any information you might have.

Hi@太郎榊原1 

The value you used for id should be correct, at least according to the documentation page:

The root cause is something else.

@Tethich 

Thank you for your reply, and I apologize for my delayed response.

I also reviewed the documentation and tried to implement it, but unfortunately, I couldn't get it to work. For now, this development has been put on hold, but I would greatly appreciate it if you could share any additional information you come across. Thank you for your continued support!

Hi @太郎榊原1 ,

Correct Way to Remove Heading Options in RTE:

The headings (H1–H6) are typically provided through the format plugin, and not as individual buttons like "h1", "h2", etc.

To remove heading options, you need to:

Target the format plugin

Remove the undesired options from its config

Working Code Example

rte: {
  plugins: {
    format: {
      features: ["p", "h2", "h3"], // only keep desired options here
    },
  },
  removeButtons: () => [
    {
      id: "bold", // works as expected
    },
    // Don't include 'h1' here — it's not a button by ID
  ],
}

Key: "h1" is not a button that can be removed via removeButtons. It’s part of the "format" plugin and must be excluded through its config.

If Using removePlugins

You could also remove the entire format plugin like this:

rte: {
  removePlugins: () => ["format"], // removes entire heading dropdown
}

But usually, it's better to keep format and just limit its options (as shown above).

This behavior aligns with the official Adobe Experience Manager RTE plugin system, where heading styles are managed via format/formatselect.

Regards,
Amit

Thank you for your response.

I implemented the changes you suggested, but I was unable to remove either the entire formatselect menu or individual tools such as certain heading options.

Our AEM as a Cloud Service environment is on the latest version thanks to automatic updates.
We are currently using “@adobe/uix-guest” ^0.8.0, and upgrading it to 1.0.0 did not make any difference.

If you have any additional information, I would greatly appreciate it.
