How to allow style tags in TinyMCE?

I thought this was an easy one, just use extended_valid_elements, right?

So, i tried this:

        public void ConfigureContainer(ServiceConfigurationContext context)
        {
            context.Services.Configure<TinyMceConfiguration>(config =>
            {
                // Add content CSS to the default settings.
                config.Default()
                    .AddSetting("extended_valid_elements", "script[*],style[*],iframe[*]")
                    .AddPlugin("code")
                    .Toolbar("code");
            });
        }

It does not work. I've tested in EPiServer.CMS.TinyMce 2.10.1 and EPiServer.CMS.TinyMce 2.13.0.

Do I really have to use an TinyMCEPluginNonVisual like descripbed in this 2013-post?

Hi Tom,

Try this-

context.Services.Configure<TinyMceConfiguration>(config =>
            {
                config.Default()
                    
                    .AddSetting("valid_children", "+body[style]").AddSetting("extended_valid_elements", "script[language|type|src]");
            });

Thanks, Ravindra! It seem to work, but I don't understand why.

This part is allowing script-tags, so it can't be that.

.AddSetting("extended_valid_elements", "script[language|type|src]");

I don't understand how adding style as a valid child of body works, I don't have body-tags inside my TinyMCE-editor. When the page is renderes style ends up as a child of body, but how can TinyMCE know that?

.AddSetting("valid_children", "+body[style]")

Can you provide some insight on why this works? I'm utterly confused :-)

Hi Tom,

I think it just checks for valid_children. Once it's valid then it applies to all the tags until you remove this from any specific tag.

I am also not sure how it is working in the background.

Adding this was enough:

.AddSetting("valid_children", "+body[style]")

Thanks! :-)
