I only used Polymorph for the first time a couple of months ago. I
don't really know what is available, but having a quick poke around what
I found was:
1. If you follow the call-chain from
UITheme>>newListFor:list:selected:changeSelected:help:
you end up in UITheme>>newListIn:for: list: selected: changeSelected:
getEnabled: help:
which uses PluggableListMorph
2. There is also PluggableMultiColumnListMorph (read its comment)
but if if you check "References" for it, it does not appear to be used
by UITheme
So the short answer seems to be - no, Polymorph doesn't out of the box
support multi-column lists.
The long answer - the components seem to be available for you to add
multi-column-lists to Polymorph yourself - perhaps just replicating the
call-chain from (1.) to end up using PluggableMultiColumnListMorph)

I got everything working besides the list update when changed. Also, is
there anyway to properly display data in columns? This is what i have:

Hello, I'm having trouble to figure out how to do this, I have a simple
window with 3 buttons, each button should change the content listed on the
list below them but I'm really not sure about how to do it.
This is the code for the window:
---
open
"Abre la ventana principal del Sistema de Gestion Bibleotecaria"
| builder contain |
builder := UITheme builder.
contain := builder newColumn: {builder newRow: {
builder newButtonFor: self action: #onPrestamosClick label:
'Prestamos' help: ''.
builder newButtonFor: self action: #onMaterialesClick label:
'Materiales' help: ''.
builder newButtonFor: self action: #onSociosClick label:
'Socios' help: ''}.
builder newColumn: {
builder newListFor: self list: nil selected: nil
changeSelected: nil help: '' }.}.
(contain openInWindowLabeled: 'Babel') extent: 600@600.

How should I define #onLabelClick to set the list to for example: Prestamo
database.
Thanks in advance.

Actually the code of the GUI is inspired on the Pharocast video on the
making of a Contact list. I wonder if the list is static since is defined
there as a newListFor and because that you can't send any message to it,
The #changed: method tells the list to get its contents again - see
example below.
I'm sure there should be a way to do it so #onPrestamosClick look like:
---
#onPrestamosClick
listMorph list: Prestamo database.

or something like that.
You didn't explicitly state your references, I presume you a referring to
http://www.pharocasts.com/**2011/02/pharo-gui-with-**polymorph.html<http://www.pharocasts.com/2011/02/pharo-gui-with-polymorph.html>
.
Note that ContactManager-**LaurentLaffront.1.mcz referred to from this
post uses...
|builder newListFor: self list:
#contacts
selected: #contactSelectedIndex
changeSelected: #contactSelectedIndex:
help: ''.|
whereas you have...
builder newListFor: self list: nil
selected: nil
changeSelected: nil help: ''
which is the key part you are missing, where the (list: #contacts) defines
the method to return the list contents, for example...
---
#contacts
^ Contact database collect: [:aContact|
', ' join: {aContact lastName. aContact firstName}
].
---
You have defined your list contents as (list: nil), whereas if it was
(list: #selectedDatabase) the following might work...
---
#onPrestamosClick
selectedDatabase := Prestamo database.
self changed: #selectedDatabase.
---
#selectedDatabase
^selectedDatabase.

good luck,
