Problem

  • As a site builder, it is not possible to customize the behavior if the e.g. image carousel widget's Swiper slider.

Proposed solution

  1. As we cannot easily invent a pattern to allow standardized manipulation of how widgets are instrumenting third-party libraries, we at least can clarify the docs on how developers can gain access to such libraries after widgets have been initialized.

Notes

  • I researched for several hours, tried various suggested solutions that all did not work. I imagine many other developers are facing the same struggle.
  • Yes, widgets provide an init hook, but it is invoked too early.
  • Swiper's afterInit event callback can only be specified in the initial parameters passed to the instance, not afterwards.
  • The proposed solution is taken from add parameters to swiper.js instance after init elementor#11067 (comment)
