I would like to check some checkbox from url parameter using default:get, but it is very unclear how to get this to work. I did find a couple of references to this from a couple of posts but they were not any clearer. Could someone please provide me with an example. Let’s say I have this field:
[checkbox plans_checkbox default:get use_label_element “Individual Education Plan” “Individual Health Plan” “504 Plan” “Behavior Support Plan” “Multi-Tiered Supports Plan” “Safety/Crisis Plan” “Other: Please list below”]

How would the url parameter look to check one of these boxes? I appreciate any assistance.
