Brief description:

the dependent form open in a dialog? There’s a module for
that.

11

bugs against the current version

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
