I would like to set the default options for a multiple selection

I would like to set the default options for a multiple selection according to a calculation. If it works, if I set the default to 1, 3, or 5.

Welcome back to the community, @chicharo80! This post discussed previously should help you solve your issue:

I’m looking for it to be through the result of the calculation so that it is like your example, converting it to non-dynamic so that the multiple selection default works, from what I’ve read, would be the correct thing to do.

You might use a (dynamic) calculate with once(…)., instead of the “default” approach.
