How to add a map in template

I am trying to create an element template for camunda modeller.
which has one of the property as below :slight_smile:

“label”: “Response Place Holder”,
“type”: “String”,
“binding”: {
“type”: “camunda:inputParameter”,
“name”: “response_place_holder”
“constraints”: {
“notEmpty”: true

Now this is a String , what if i want it to be a MAP kind of thing where i keep pressing a “+” button and it keeps adding rows for me with a key and value.
Is there a way to do that.

@shashank19aug you can refer this docs for camunda-modeler-element-templates.
