Hello , I am part of the team “kitedor.info” with @babyfooter.

I have made a modal window on our discourse.  
She is opened by clicking on a menu link in the header.

This is the HTML of the modal window in the header css section :

```
<!-- Modal One -->
<div class="modal1">
  <input class="modal1-open" id="modal-one" type="checkbox" hidden>
    <div class="modal1-wrap" aria-hidden="true" role="dialog">                   
    <label class="modal1-overlay" for="modal-one"></label>       
          <div class="modal1-dialog">
            <div class="modal1-header"><h2>Les News de KiteDor</h2>
            <label class="btn-close" for="modal-one" aria-hidden="true">×</label></div>
                <div class="modal1-body">...</div>
         </div>
    </div>
  </div>

```

I wish I could open this modal window from a post but the problem is, post does not accept this css tag :  
for=“modal-one” and automatically clears it.

Here is the html that I’ve put in the post :

`<label for="modal-one"><a >News</a></label>`

Can you help me , it is a way to gain acceptance for = " modal -one " in a post without whatsoever erase, to force the CSS to just accept this tag for = “” .

Thank you in advance for your help and sorry for my bad english.

Hello , I advance a little on my problem and I think I found the solution, but I can not put in a pratique.  
I need help.  
All my tests are performed locally on my mac and not on the server.  
I think the solution is here:  
[https://meta.discourse.org/t/whitelisting-some-html-tags/24280](https://meta.discourse.org/t/whitelisting-some-html-tags/24280)

But I don’t understand how.  
I have edited the file: **“/var/www/discourse/app/assets/javascripts/discourse/lib/markdown.js”**  
and add this line : **Discourse.Markdown.whiteListTag(‘label’, ‘for’, ‘modal-one’);**  
But `for="modal-one"` disappears again in tag

I write : `<label for="modal-one"><a >News</a></label>` in the post  
**and** the inspector gives that : `<label><a>News</a></label>`

Where I am wrong please ?

Thanks.

Do not manually edit files within the Docker container. Instead, write a small plugin for this as mentioned [here](https://meta.discourse.org/t/whitelisting-some-html-tags/24280).

That looks plausible 🙂

[Here](https://github.com/fefrei/discourse-teamup) is a similar plugin I’m using myself, for reference.

No

The last parameter is a regular expression, not a string

Try `/modal-one/` _not_ in quotation marks.

A plugin is no longer needed to render a modal. It can be done in a theme or theme component.

More information about that here:

> [@Render modal from theme client-side plugin API](https://meta.discourse.org/t/render-modal-from-theme-client-side-plugin-api/94305):
>
> Is there any way to render a modal from the theme javascript? I was looking forward to render a modal similar to the one that shows up when changing avatar. Example: \<script type="text/discourse-plugin" version="0.8"\> api.onPageChange((url, title) =\> { if (condition) { renderModal; } }); \</script\>
