How to add the custom task(service task implementation) in web modeler pallet

In flowable how to add the custom component(implemented using service task) to web modeler and only selective properties should be shown to the user for modelling, rest of the properties should be prefilled but shouldnot show to user.

Please suggest some examples if possible.

Have you tried searching the forum for ‘custom task’:

Actualy before Posting this question I found this question similar to my requirement but I need fileds in service task should be presented for user to fill ,rest of the properties like class name etc are to be prefilled and not to available for users,as i am defining this custom task so user should just drag and drop no need to enter those properties.

So I am not finding exact solution as per my requirement. According to the topic that i have mentioned here I got to know that by editing stencilset_bpmn.json I can add custom task to palette but it is present in source code not in the war file that is generated from source code.
