Hi there,

I’m trying to create a custom textarea button. I just used the sample and it doesn’t work.

The plugin correctly appears in the system panel view.

index.js :

```auto
window.panel.plugin("adrienpayet/panel-text-comments", {
  textareaButtons: {
    highlight: {
      label: "Highlight",
      icon: "wand",
      click: function () {
        this.command("toggle", "<mark>", "</mark>");
      },
      shortcut: "m",
    },
  },
});

```

The blueprint :

```auto
    fields:
      edito:
        type: textarea
        buttons:
          - highlight

```

I also declared the plugin in its index.php :

```auto
<?php

Kirby::plugin('adrienpayet/panel-text-comments', []);

```

Is there any mistake ?

The one thing I see that I don’t think is right is that you don’t need `window.panel.plugin...` which should just be `panel.plugin("adrienpayet/panel-text-comments", { ` etc.

There’s an open bug about textareaButtons because if you use them in more than one textarea field in a single blueprint, it causes the page to endlessly spiral.

I’ve noticed that too.  
As soon as I integrate my custom button, my backend freezes

[I did it exactly the same way](https://getkirby.com/docs/reference/plugins/extensions/textarea-buttons)  
Any Updates on this one?

**edit:**  
The error occurs as soon as more than one text area contains a custom button.  
Think that’s a bug.

I was browsing the forum today and found a similar issue, where the Kirby sanitizer needs to be prepared for the custom button.

Maybe it helps someone here:

> [@Custom writer marks in Kirby 4](https://forum.getkirby.com/t/custom-writer-marks-in-kirby-4/31236/2):

> The docs should probably mention this. But “unknown” (to Kirby) tags are filtered out by the sanitizer. You can allow tags in your plugin’s index.php \<?php Kirby\Sane\Html::$allowedTags['mark'] = true; Kirby::plugin('mark/eg', [// ...]);

Has this issue ever been resolved? Anyone found a solution? I’ve just spent hours thinking the issue is me but I am starting to doubt that.

Could you please post the code you tried? I just tested the code example from the docs, which seems to work fine, at least in Kirby 4.5.0.
