Introduction
You can set fields to show or hide based on values selected in another field using a custom configuration.
The rules added for skip logic are only reflected on add/edit pages. The overview page is a superset of all fields described in the data dictionary.
Below are some examples of how this feature can be used.
Examples
Show custom field based on the value of another custom field
Show the field 'Relation To Proband' only if the value of field 'Proband' is equal to 'No'.
Example code
{
"name": "cpr.participant.extensionDetail.attrsMap.DD15",
"caption": "Relation To Proband",
"type": "dropdown",
"optional": true,
"showIf": {
"op": "AND",
"rules": [
{
"field": "cpr.participant.extensionDetail.attrsMap.RB10",
"op": "==",
"value": "'No'"
}
]
},
"listSource": {
"apiUrl": "forms/permissible-values",
"selectProp": "value",
"displayProp": "value",
"queryParams": {
"dynamic": {},
"static": {
"formName": "kMCParticipantExtension",
"controlName": "DD15"
}
}
}
}

Screenshot when the field is shown:
Show custom field only on create aliquots page
Display the custom field 'Storage tube' field while creating the aliquots
Show custom field when the visit date is greater than specified date
Show the 'COVID-19 Test Date' custom field only when the visit date is after 23 January 2020.
Show custom field based on specimen lineage and type
Display 'Upload image' custom field when the specimen lineage is 'New' and the specimen type is 'Whole Blood'.
Example code
{
"name" : "specimen.extensionDetail.attrsMap.upload_image",
"caption" : "Upload image",
"type" : "file",
"optional" : true,
"showInOverviewIf" : "useShowIf",
"showIf" : {
"op" : "AND",
"rules" : [ {
"field": "specimen.lineage",
"op": "==",
"value": "'New'"
},
{
"field" : "specimen.type",
"op" : "==",
"value" : "'Whole Blood'"
} ]
}
}
The field looks like the below on the specimen overview page:
Show/Hide custom field based on specimen lineage and multiple type condition
Made Method field shows only if the Lineage=Aliquot and Type is RNA or DNA
Example code
{
"name" : "specimen.extensionDetail.attrsMap.made_method",
"caption" : "Made Method",
"type" : "dropdown",
"showInOverviewIf": "useShowIf",
"showIf": {
"op": "AND",
"rules": [
{
"field": "specimen.lineage",
"op": "==",
"value": "'Aliquot'"
},
{
"field" : "specimen.type",
"op" : ".search('RNA|DNA')!=",
"value" : "-1"
}
]
},
"optional" : true,
"listSource" : {
"apiUrl" : "forms/permissible-values",
"selectProp" : "value",
"displayProp" : "value",
"queryParams" : {
"dynamic" : { },
"static" : {
"formName" : "epidemiology_specimen_custom_form",
"controlName" : "made_method"
}
}
}
},
Show/Hide custom field – Using Regex Matching
Show the 'Lived Name' custom field only when the PPID starts with 'J'.
Example code
{
"name": "cpr.participant.extensionDetail.attrsMap.lived_name",
"caption": "Lived Name",
"type": "text",
"optional": "true",
"showIf": {
"op": "AND",
"rules": [
{
"field": "cpr.ppid",
"op": ".search('^J') !=", // Modify the regex in single quote as per requirement.
"value": "-1"
}
]
}
}
