Create Multibox with selected Fields

[#1]

Hi everyone,

I imported a csv-file that looks like this:

ID	Client
1	a
2	a
3	a
4	b
5	c
6	d
7	e
8	e
9	e
10	f
11	g
12	g

You can assume that each ID is unique.

Now I want to create a multibox that lists all distinct Clients with at least 2 realted IDs. Clients with only one related ID should be invisible.

The result should look like this:

Client	ID
a	{1,2,3}
e	{7,8,9}
g	{11,12}

Clients b,c,d,f are omitted..

Thanks in advance.

EDIT: Is there also a way to count the amount of distinct Clients with at least 2 related IDs?

Creating a straight table that looks like that can be done with:

    calculated dimension Client: if(aggr(count(distinct ID),Client)>1,Client)

    expression ID: '{' & Concat(ID,',') & '}'

Check the option Suppress When Value Is Null for dimension Client

But you can't create a multibox automatically the way you want. I also don't understand what you would want with such a multibox even if it could be created. What do you intend to select and what should that selection do?

Thanks for your fast answer,

The data comes straight from an import  held in a flat csv-file. Every pageview is stored with an ID and and assigned Client. Now I want to list all clients with at least two pageviews (i.e. ID).

As I see from your reply multiboxes seem to be the wrong choice for that.
