Template

Item templating

Popup items can be customized using the beforeItemRender event. The item render event triggers while rendering each popup action item. The event argument will be used to identify the action item and customize based on the requirement.

The following popup template is customized using beforeItemRender event by appending span and div element on each li rendering:
