Problem/Motivation

The component library in UI Patterns breaks when this module is installed.
The menu-tree has required props menus and exclude, but UI Patterns Library doesn't provide a default for them, and ComponentValidator->validateProps() throws an error.

Steps to reproduce

Enable Menu Trees and UI Patterns Library.
Go to the component library.
See whitescreen errors.

Proposed resolution

Add default values of empty array/string.

Remaining tasks

User interface changes

API changes

Data model changes

I see that an example has been added for those props, but that doesn't work with the component library.

UI Patterns Library is working. It only renders the Main menu label, since there are no default links specified.

SDC Styleguide isn't working, but that's due to an error in how it handles complex properties. It's trying to put them in a text area.
I added a related issue for that.

This is a case where the UI Patterns Library can't really provide a better demo from default values because we don't want to provide irrelevant dummy content as the default. It makes more sense to do that as a story.

In the patch, you have main:standard.front_page as an example link. This is only in the standard install profile and may not exist. Maybe use links from system instead?

SDC Styleguide can create demos with a drush command. That sounds a lot closer to what is needed to set up realistic styleguides

I think it should be examples, not example?

Looks like some modules like SDC Styleguide, SDC Component Library are using examples.

I'm not sure what you mean by:

SDC Styleguide isn't working

I have never used the module and I'm not sure what to expect. It does not crash the site at least :-)

Now it doesn't work in SDC Styleguide... Looks like a bug on their end though.

Ok, I will review the fix. Can we consider this done then?
