Add a declarative way to set applyAuthorStyles on a element's shadowRoot

applyAuthorStyles may be set on the element's prototype.

Opening this back up as we never came up with a declarative way.

My use case is <polymer-ui-submenu-item>. From a label attribute, it produces shadow dom that contains (<polymer-ui-menu-item>):

I want to override stylings for that element, but can't with JS:

created: function() {
  this.$.menu.children.forEach(function(el, i) {
    if (el.localName == 'polymer-ui-submenu-item') {
      el.shadowRoot.applyAuthorStyles = true;
    }
  });
});

Instead, an attribute would be nice:

<polymer-ui-submenu-item label="Elements" apply-author-styles>
  <polymer-ui-menu-item>Polymer</polymer-ui-menu-item>
  <polymer-ui-menu-item>Test</polymer-ui-menu-item>
</polymer-ui-submenu-item>

Can <polymer-element> support a apply-author-styles attribute?

Has the declarative way been implemented. I would like to see that.

Also, please be sure to document this when you implement it. Setting applyAuthorStyles on the prototype works, but isn't mentioned at http://www.polymer-project.org/polymer.html or http://www.polymer-project.org/docs/polymer/styling.html.

applyAuthorStyles is a shadow feature so it's not part of the core
reference. It's documented in my styling article:

Ah, yes. I'd expected one of the reference pages to list the recognized fields of 'prototype', rather than leaving it to an introductory article.

Yes, the applyAuthorStyles is a feature of Polymer that enables that flag
for Polymer-created ShadowRoots. So I agree it should be listed as a
Polymer property (while the details of the actual effects can still be in
the ShadowRoot docs).

Added these to the reference as well: Polymer/old-docs-site@8b744f8

Thanks!

Can we close this now that applyAuthorStyles is gone? Has it been removed from Polymer?

[addyosmani]

It's been removed from Polymer in googlearchive/polymer-dev@67ac33e. I would say it should be safe to remove.

[ebidel]

Closing :)
