How to choose multiple options in a netlogo chooser?

Question

I'm trying to choose multiple options from one chooser in netlogo. Does anyone know if that is possible and if it is how to do it?

I have a slider which gives me a number of strategies I want. Those strategies I have to choose with a chooser. So if my slider gives me two, I have to choose 2 strategies etc. — Amber, Mar 20 '18 at 12:31

One possibility is to use the eXtraWidgets (xw) extension, which allows you to define multichoosers like this:

A few words of warning:

The extension only allows you to put that kind of widget on a separate interface tab.
The extension is fairly powerful, but there is a bit of a learning curve to it: widgets need to be declared programmatically, you can't just drop them on the interface.
As of today, the 6.x version of the extension is still in beta. The author has had limited time to iron out all the kinks.
I am the author of the extension.

If xw doesn't meet your needs, you can most likely achieve what you want by using a series of switches, like this:

It's not quite as pretty and convenient, but it can get the job done.
