Items without a Value - Hide in Display & Document Generation

Greetings,

I was originally going to reply to this thread (https://my.skybow.com/hc/en-us/community/posts/360007690360-Exclude-list-items-from-document-generation), but with it being 5 years old and my question being slightly different, here we are...

I am wanting to Hide (not Visible) items/columns which do not have a Value. The answer very well might be to .length <>+ # in someway.

Lets say I have 20 image columns...

Picture1

Picture2

Picture3

...

Picture20

Lets say I have 20 short text columns...

CrewMember1

CrewMember2

...

CrewMember20

Display Form - What would be the Visibility method, for each item, to only display items which have a Value (an Image is attached / Crew Member name was populated)?

Document Generation Template - Same question, but for Document Generation. (I suppose this would involve an IF statement, but couldn't find any documentation)

For Document Generation, it would be similar to this, but instead of checking for a Choice Value, check if it has a Value at all:

--- --- --- --- --- --- ---

While trying to find an answer for the above, I ran across these 2 posts:

1. https://my.skybow.com/hc/en-us/community/posts/360007687860-Expression-for-checking-if-any-sub-list-entries-have-been-made-on-the-form-Needing-to-start-a-specific-workflow-if-new-items-have-been-added-to-the-sublist-on-my-form 

var webpartId = "YourSubListWebPartId";
var webpartSelector = "[ard-webpart-id=" + webpartId + "]";
var gridController = jQuery(webpartSelector).data('Controller');
var grid = gridController.InstanseData;
var itemsCount = grid.GetAllRecordIds().length;

2. https://my.skybow.com/hc/en-us/community/posts/360007691959-Display-Form-Suppressing-sub-list-if-no-sub-list-entries-I-would-like-to-suppress-the-sub-list-on-my-display-form-if-there-are-no-sub-list-items-applicable 

var webpartId="your webpart id";
    var webpartSelector = "[ard-webpart-id=" + webpartId + "]";
    var gridController = jQuery(webpartSelector).data('Controller');
    var grid = gridController.InstanseData.GridControl;

    return grid.GetSpCsrRenderCtx().ListData.Row.length > 0 ;

These are both older posts, and seem to use the Ardevia syntax...

However, they both look extremely useful, and I was wondering if ya'll could possibly provide updated samples, using the Skybow syntax. (I am guessing they are different.)

Much appreciation as always,
