Hi!
I am trying to get the data from a multi-dropdown input on a form into a Thing. I’d like this data to end up in this format: [Recursos Humanos, Operación]. Just separated with commas
Has anyone used this input to pass data to Things?
Thanks for any help!
Sure, that’s just:
Multidropdown's value
this is a list of the same datatype as the Multidropdown’s “Type of Choices”.
E.g., If your multidropdown is configured like this:
… Multidropdown SECTOR's value is a list of type Industry Sector.
(Of course, if there are no selections, that list will have no items in it – it will be a zero-length list. If there are one of more selections then the list will have that many items in it. You can check if a selection has been made by Multidropdown SECTOR'S value:count > 0 or by Multidropdown SECTOR's value: first item is not empty 
either of those conditions will be true/yes if a selection has been made.)
Continuing on: The tags you see in the Multidropdown come from “Option caption” (refer to screenshot above – there, my option caption is coming from the Name field). Those will be of type text of course.
If you want a joined list of texts representing those tags, you can do:
Multidropdown SECTOR's value's Name
this will be a comma separated list of the Names displayed in the multidropdown’s selection (it might look like “accounting, jet propulsion, medicine”.
If you desired a different separator than comma, you could do:
Multidropdown SECTOR's value's Name :joined with "some other string"
e.g., Multidropdown SECTOR's value's Name :joined with | "
would yield us something like “accounting | jet propulsion | medicine”.
