Text Entry with Suggested Values

Thanks for filing this and for the link! I think we have the pieces needed, I just need to figure out the api.

I just need to figure out the api.

Perhaps just add a "suggested values" field to TextEntryWidget.InitOptions?

suggested_values: ?[]const []const u8 = null,

What I'd like to do is have the api be more like:

• make the textEntry
• make a separate "suggestion dropdown" widget that gets it's location off the textEntry
• the using code adds suggestions to the list
  • this way the suggestions don't have to be static, and
  • it can dynamically filter based on what's already in the textEntry
  • also the filtering is in the app code not dvui code (but we would offer a built-in one)
• detect if the user has selected an entry and populate the textEntry with that value

But there are still a lot of unknowns that can only be figured out by going through it:

• How to know when to show the suggestions dropdown
• How to make keyboard navigation work (pressing down while in the textEntry should move the focus to the first suggestion?)
• Can it be a separate widget, or does it need to wrap the textEntry?

I'm sure it'll end up really nice, but it's going to take some time.
