Often times, being able to add custom CSS to fields isn't enough. We also find ourselves needing to add various custom attributes directly to the underlying input fields, such as:

• readonly
• placeholder
• autocomplete
• autofocus
• novalidate
• data-*

We currently add these using JavaScript, but this can result in overly long JS sections that are hard to navigate, and isn't great from a performance perspective.

It would be nice to be able to define custom attributes directly in the form designer, in the form of [Attribute Name]: [Attribute Value], where the latter can come from a dataset.
