App Components - Add Custom HTML?

Is there any way to display custom HTML through an app component? Specifically I would like to expose a file picker from an external application. The picker is a JS redux application that can be embedded into web apps. I essentially want to replicate the functionality that the “Attach a file” option does for Google Drive, One Drive, etc.

Hi @Doug_Gillespie and welcome to the forum,

No, there’s not. You’re limited to the 10 type of form fields listed here in the API docs.

I suppose you could theoretically accomplish it using a Typeahead field, but you couldn’t use your existing JS application; you’d have to write code to programmatically read the folders/files and populate/manage the Typeahead control.

Thank you for confirming!
