I recently installed a new Orchard Field written by Andre Rodrigues.
Youtube Field - v0.91
Works like a charm, however breaks the layout of the page (Tested in Google Chrome and not bothered with others as this was broken).
The Field originally renders as
    <div class="youtube-field">
        <iframe 
            width="@Model.ContentField.Width" 
            height="@Model.ContentField.Height" 
            src="http://.../@Model.ContentField.Identifier?hd=1" 
            frameborder="0" 
            allowfullscreen />
    </div>
    Which breaks the layout. So I updated it to:
    <div class="youtube-field">
        <iframe 
            width="@Model.ContentField.Width" 
            height="@Model.ContentField.Height" 
            src="http://.../@Model.ContentField.Identifier?hd=1" 
            frameborder="0"
            allowfullscreen="true"></iframe>
    </div>
    Fixed!
I am always interested in hearing back from those who read my blog. Please leave a comment if you found this useful, want to suggest any changes to my code, or anything else! Thanks!
