Hi,

I tried to add a Disclaimer on a specific Category. I had the Idea to have a “banner” - like  
`This is User's first post - let's welcome the new member to our community!`  
or  
`It's been a while since we've seen USER - the last post was 1 year ago.`  
above each Post.

I tried to archive this with:

> **common/head\_tag.html**
>
> ```js
> <script type="text/discourse-plugin" version="0.8">
> api.decorateWidget('post:after', (helper, args) => {
> if (args.topic.category_id === 51) { // My Category
> const $post = helper.find('.cooked');
> const disclaimerText = api.decorateCooked(helper, args, settings.MY_DISCLAIMER);
> $post.prepend(`<div class="disclaimer">${disclaimerText}</div>`);
> }
> });
> </script>
> 
> ```

Just to be complete here is the

> **settings.yml**
>
> ```yml
> MY_DISCLAIMER:
> type: string
> default: 'This is a Category that comes with limited warranty and is to be used at your own risk.'
> description: Disclaimer Text for Category
> 
> ```

and there is also `common/common.scss` with the `.disclaimer` class in it.

But when I active that the Post itself is no longer shown, the content area is just blank.

Thanks for any help!

Is it blank in the source too?

Hi, welcome back!

If you see blank, it’s because you have an error. `find` doesn’t exist in the `helper`.  
You can usually see that in the browser console (F12).

You probably want something like that:

```js
api.decorateWidget('post:before', (helper, args) => {
    if (helper.widget.model.topic.category_id === 51) {
        return helper.h("div.disclaimer", settings.MY_DISCLAIMER)
    }
});

```

or using raw HTML:

```js
const RawHtml = require("discourse/widgets/raw-html").default;

api.decorateWidget('post:before', (helper, args) => {
    if (helper.widget.model.topic.category_id === 51) {
         return new RawHtml({html: `<div class="container">${settings.MY_DISCLAIMER}</div>`})
    }
});

```

You can read [this post](https://meta.discourse.org/t/how-to-add-customer-html-after-post-1/123068/2) explaining how this `h` helper works.

You can do the following if you want to add some HTML before the cooked content:

```js
api.decorateWidget('post-contents:before', (helper, args) => {
    const { topic } = helper.widget.findAncestorModel();

    if (topic && topic.category_id === 51) {
         return helper.h("div.disclaimer", settings.MY_DISCLAIMER);
    }
});

```

Thanks @Arkshine, that helpt a lot!

I used the following Code due to I want to display the Text above all like the other, mentioned banners.

```plaintext
api.decorateWidget('post:before', (helper, args) => {
    if (helper.widget.model.topic.category_id === 51) {
        return helper.h("div.disclaimer", settings.MY_DISCLAIMER)
    }
});

```

Greetings!
