Is it possible to use toolset to build a custom form that lives on the admin dashboard? I want clients to fill in some general site info in the dashboard so that I can call up that data via shortcode to display elsewhere on the site.
If not, I think I will build a custom type and link to it but having something editable on the admin dash would be helpful.
No, this is not possible.
It may be possible with some hacks and calling Forms by PHP in the WordPress Admin areas, but it is entirely not intended for this.
It is intended to bring the admin to the front end, with it's forms, that you can do.
But not the opposite, edit in the backend with those forms.
Well, that's a bummer. This is the first time I've found something toolset can't do. lol
I think it would be a nice consideration for the future.
