Use multiselect input in a dashboard?

[m0rt1f4g0]

Hello.

I have three lists of names of different technologies, I would like to put the technologies in a menu or multiselect so that when I select each technology it brings me the names of each one that is selected, for example:

My list is:

m0rt1f4g0_0-1675411730875.png

My multiselect input is:

m0rt1f4g0_1-1675411786803.png

When selecting each option, I would like it to show me all the users like the following table:

m0rt1f4g0_2-1675411988987.png

try doing the following

| makeresults
|eval input = "$ms_Be1Voild$" //This is the token of my multiselect input
|eval array = mvjoin(input, ",")
|fields array

But the result is the following:

Active Directory,o365,Windows

Could anyone help me please.
