Count and display items of a collection

Question:
I need to display the number of items of a collection, grouped by customer

Product:
Wix Editor

What are you trying to achieve:
I use Velo and Wix Editor on a site which lists about 500 jigsaw puzzles.
Each puzzle is assigned to an “owner”, and can be created, deleted, or traded.

SO, I use a collection : “myList”, each item is a puzzle with different informations as : “number of pieces”, “brand”, “owner”, etc…

I need to display the number of puzzles of each owner.

My experience of velo and javascript is too weak to figure out how I can do.
I would like some help, if possible.
Here is my site :

What have you already tried:
Velo WIx documentation - this forum

Additional information:

The displaying the number of items should be pretty straightforward, but depends on other factors regarding the best approach.

Are you able to expland a little further on the setup?

  • Is this just a standalone number, or are you displaying it alongside a table of data?
  • Are you using other code on the page?
  • How should the number be calculated (e.g. are you needing to filter the data in some way)

Sorry, I wasn’t alerted by your answer, so I didn’t go on with this issue.
Now, I work back on it, I can tell you :

I need to display the number of puzzles of each owner.

There is a dropdown menu that allows people to filter puzzles by owner in the home page.

I would like to display the number of puzzles for each owner in this dropdown menu. And then, puzzles are filtered.

I think I can configure my account to be alerted when answers appears, I’ll look for how to do it

Thank you for having considered my request.
