Cascading Gallery Filters with two SP Lists

(0) ShareShare

Posted on by 580

Hi All, 

 

I'm creating a knowledgebase article (KB) side to an app we've developed. I'm having to create it in a way that allows certain users access to create new KB categories, and then create articles against those categories. 

So I have two SP Lists: KB Categories and KB Articles. I have a lookup column in the KB Articles list, called 'Category' - this is connected to the 'CategoryName' column in the KB Categories SP List. 

 

When a user first navigates to the welcome screen of the KB - they are presented with a horizontal Gallery which is connected to the KB Categories List. This will show them all the available categories.

I would like for them to be able to select a category, navigate to the next screen, and the gallery on that screen, displays all the articles against that category.

From there, they'll select an article to open and read. 

 

But I'm struggling to get the gallery's to reference and filter between the two SP Lists. 

I've thought about my approach on this, and the reason I have created the two lists is because of the managers (user experience) when creating a new category and then being able to create a new article. 

 

I've referenced before with dropdown fields between two lists using ForAll(Ungroup - but not with Galleries. 

 

Any help appreciated!
