Ummm … the short is Yes, anything’s possible.

However, unless I’m reading this completely wrong (which would not be unusual), you want 3 “dropdowns” on a web page, with interaction between said “dropdowns”?
As in … you visit a Cars page (or any other page for that matter) and somewhere on it you see 3 SELECTs :

1. the 1st one presents a list of makes (Audi, BMW, etc)
2. the 2nd then presents a list of the models related to the OPTION selected in the 1st
3. then the 3rd presents a list of types related to the OPTION selected in the 2nd?

CMW won’t do that for you :

• CMW has no option for output as a SELECT (if that is what you meant by “dropdown”?)
• CMW doesn’t provide any front-end javascript, therefore there is no in-built interaction between instances – you’d have to provide it yourself

You could use 3 instances of CMW to provide filtered levels of your menu (as hierarchical lists) : 1st would be makes, 2nd would be makes & models, and 3rd would be (at least) models & types. Then use javascript and CSS to hide non-relevant items/sub-lists at the outset, and revealing items as choices are made from the 1st then 2nd lists. The 3rd list would presumably then be the only one that performs actual navigation (to the relevant make-model-type page).

As I said, it’s possible … but a bit of a faff!
Given that you’d have to provide the interaction anyway, I think you’d be better off writing a short plugin to do specifically what you want.

PS : If I’ve got this all wrong and, as an example, on the Audi page you want a sub-navigation menu listing all the Audi models (maybe even with their associated types), then that is where CMW could be ideal (children of current page, 1 or 2 levels)? Or to list all the makes on any page? Or to list the relevant types on any make-model page? But again, if you want interaction (in-browser filtering) between instances, then you need to provide it yourself.

No problem.

It sounds like you want an interactive menu?

CMW does not provide interaction, for the same reasons that it doesn’t provide styling : everybody wants something slightly different.
You might find this post – …/support/topic/collapse-and-expand – of use?

One small note : if the Galleries menu item links through to a page, as well as being the parent of other menu items, then for a click-expandable menu you will need to have an extra collapse-expand element within the item’s HTML output (because clicking the item itself should navigate to the Galleries page). For a hover-expandable menu you doesn’t necessarily need the extra element (but you could run into problems with touch devices?).

I am unable to reproduce this.

I have loaded the latest Storefront theme, on WordPress v4.3.1, and I have no problem accessing the customizer (from any admin page, for whatever reason).

Since posting here, you have posted on the Storefront theme’s support forum, and on the Nav Menu Roles plugin’s support forum. Both posts are related to customizer problems, and both posts appear to indicate that Nav Menu Roles might be the cause of the problem : does this mean that you no longer have an issue with CMW?

PS. I also loaded the Nav Menu Roles plugin (latest version), and still encountered no problems.

Try setting the Alternative, based on Current Item is Not in Menu?

I’m sorry but No, not using the options.
The closest decision-making option CMW provides is the ability to switch options based on the presence/absence of a Current Item, and even then you can’t switch from one menu to another.

CMW does have a filter that might be used, if you could decide on the actual test that needed to be made…

add_filter( 'custom_menu_wizard_settings_pre_widget', 'your_filter_function', 10, 2 );
function your_filter_function( $instance_settings, $widget_id_base ){
  //$instance_settings are the sanitized options for this CMW instance
  if( [your_test_criteria] ){
    //prevent this CMW instance outputting anything...
    $instance_settings = array();
  }
  return $instance_settings;
}

…which could prevent/allow the running of any CMW instance. You’d need two separate instances of CMW – one based on Menu 1, the other based on Menu 2 – and your test criteria would have to include inspection of the widget settings to see which instance you’re filtering at the time, as well as somehow reliably determining which page you’ve come from. (Bear in mind that the filter gets called once, separately, for each instance of CMW, and that it runs before any of WordPress’s nav menu functions get called).
If you’re comfortable with PHP then you could add such a filter to your theme’s functions.php (preferably a child theme!).

Thank you for the report.
However, if you are still getting this warning I would suggest that you try deactivating some of your other plugins until the message disappears … because CMW is not the culprit.

Making a menu horizontal menu is more a case of styling than content. Unfortunately, CMW doesn’t do styling! You can use CMW to filter what gets shown in your menu, but for how it gets shown you need to search for some CSS that will make the list horizontal, and stick it in your theme’s stylesheet (preferably a child theme).
