We have seen that there is a problem when we use the checkbox format on Elab. The checkbox type does not allow multiple choices to be selected using the options attribute.
"Subject behaviour (post-trial)": {
"type": "checkbox",
"value": "",
"options": [
"Agitated",
"Resting",
"Sleeping",
"Sparse trials"
],
"position": 21
},
The idea would be to create several checkboxes for each choice in the list of options I think
