You may use the Custom Layout editor and create the link using the HREF tag. For instance for the first attachment of your event you may write:

<a href="{{Uploaded File Href 1:JEV_FILE_HREF_1}}" target="_blank">

    Link to file

</a>

Also if the attachment is a pdf, it will automatically be opened in a new window/tab

Hello carcam, thank you for your answer. I tried to do as you advised. But in icalevent.detail_body ,
icalevent.detail_body or icalevent.list_row ididn't get the right result. What would be the right place to put in the link?
Is the Syntax correct? "
<a href="/{{Uploaded File Href 1:JEV_FILE_HREF_1}}" target="http://www.casinoverein.eu/images/pdf/euskirchener-doko-regeln.pdf">
</a>"
Thank you for your help.

There is a little typo in my code. You should use:

<a href="{{Uploaded File Href 1:JEV_FILE_HREF_1}}" target="_blank">

    Link to file

</a>

That code should work. Otherwise, please show us a page where this is showing and we can debug the issue from there.

Thank you for your answer. But I dont get it. Please see the attachment.

Can you please provide Super User access to your site? The layout is not showing now the target attribute and I want to check why.

For providing Super user access I need your EMailadress.

The actuell target is "Der Neue Mensch 2017.pdf" instead of "euskirchener-doko-regeln.pdf".
Thanks so ar.

Please use carcam@jevents.net
