Common keys on every field: id (auto-generated), type, label, name, required, placeholder, css_class, conditions.
Conditional logic
Every field accepts a conditions rule that shows or hides it based on other fields' values.
json{
"action": "show",
"match": "all",
"rules": [
{ "field": "field_abc", "operator": "is", "value": "Yes" },
{ "field": "field_xyz", "operator": "is_not_empty" }
]
}| Operator | Effect |
|---|---|
is | Equals |
is_not | Does not equal |
contains | Value contains string |
not_contains | Value does not contain string |
greater_than | Numeric > |
less_than | Numeric < |
is_empty | No value |
is_not_empty | Has any value |
action is show or hide. match is all (AND) or any (OR).
Logic is evaluated client-side in real time, then re-evaluated server-side on submit so hidden fields cannot be force-submitted by bypassing JavaScript.
