We want to have a Custom Dropdown field in the form designer and also show the selection list by fetching from external system using REST call. Is this possible ? what are the files we need to look ?
Yes sure. You can add the new form field in the form-builder.js file in the flowable-ui-modeler-app. The new form field also needs to be added to the flowable-form-model FormFieldTypes class. For the task app you need to add the support for the new form field type in the form-element-template.html file and the REST call logic to the render-form.js file.
Thanks Tijs for quick reply , i will now try creating custom field.
