• Brief description:
  • Have you ever wanted to use Inline Entity Forms but have the dependent form open in a dialog? There’s a module for that.
• Module name/project name:
  • IEF Complex Widget Dialog
• Brief history
  • How old: created in Mar 2020 by dataweb, though recent releases are by Chris Lai (chrisck), a fellow Canadian
  • Versions available: 2.1.1 and 2.2.2, the latter or which is compatible Drupal 8.8 or newer, all the way up to Drupal 11
• Maintainership
  • Actively maintained, latest release in the past month
  • Number of open issues: 4 open issues, none of which are bugs against the current version
• Usage stats:
  • 273 sites
• Module features and usage
  • When you install the module, your Inline Entity Form widget configuration will have a new checkbox, to “Enable Popup for IEF”
  • Includes specialized handling for different kinds of entities, like nodes, users, taxonomy terms, and users
  • Will handle not just the creation forms, but editing entities, and also duplicating or deleting entities
  • Not something you would always need, but can be very useful if the form you want to use for entity or even parent forms that are complex
  • I should also add that IEF supports form modes, so often I’ll create an “embedded” form mode that exposes fewer elements, for example hiding the fields for URL alias, sticky, and so on. So I would start there, but if the content creation experience still feels complex, then IEF Complex Widget Dialog might be a nice way to help
