I’ve already seen how to add another group like this one in the docs :
if (is(element, ‘bpmn:StartEvent’)) {
group.entries.push(entryFactory.textField(translate, {
id : ‘spell’,
description : ‘Apply a black magic spell’,
label : ‘Spell’,
modelProperty : ‘spell’
}));
But i can’t figure out how to add another type to the combox of the form i mean to add a select or a radio or checkbox inside the form.
