Input boxes are absolutely necessary for testing functionality and UI design. There is no way to test this right now in XD. Along with any kind of selection elements like a check box or radio button. These are absolutely necessary to develop a prototype. The point of the prototype is to replicate the functionality of an actual site or app. Without many more features, XD just isn't shaping up.

Yes please add this feature. This is the 1 reason our company uses Justinmind, and would not use XD until this feature is added (if it will be added). Thanks for listening.

yes! this would be very helpful. our testers often try to type in the text fields and their feedback is affected because it doesn't feel natural to click and suddenly have all the fields filled.

I work on Axure and it will be very helpful for having few basic form elements to help our UX testing folks better.
Check box
Radio button,
Text field,
Drop-down,
Accordions, tabs etc

Yes! The same for radio-buttons and checkbox.

Yes please add this. Along with ability to mimic smart search results. Time for a tid bit more complexity. We can handle it

atomic has this feature, where you could style a text input as a box of input and then use the same input field styling it as plain text in another screen. This way you can carry the users input to other screens.

Proto.io, Atomic, and Justinmind support this feature (I think Invision Labs Craft Prototype for Sketch may as well), and it makes such a huge difference in the realistic feel of the prototype.

I love the idea of applying different actions based on different strings. Brilliant!

This feature would lift Xd to a truly first-class prototyping tool.

Vote for it if you want it! :)

+1 To all the comments in this thread. Testing user workflows - think the kind you make in BPMN - gets old FAST when you tell the participant, "Imagine that you have typed in..." Start with just being able to designate a shape as a text input field. But the comments here about if-else, and reusing strings is subsequent steps are right on.

please add this! Being able to test text input would be GREAT and make XD stand out. I have been trying different prototyping programs to try and test this for a project and it is very frustrating.

Yes, this!

Setup Text Layers to automatic transform into live input fields during preview.
*Configure different keyboard types and define behavior for the return key.

Axure is a very good example. Testing forms is a top priority issue for websites, e-shops, web applications! For everything!

I would like to see if-else variables. Like an autofill features which pops when typing certain characters in an input field. See axure as an example.

If 'character' = 'b' show: Book, belt, balloon
if 'character' = 'bo' show: book

Stripping down based on input with customisable variables.

fillable text fields, a better viewer without web nav bar on mobile devices, and other reqs

looking forward to updates. hoping for more robust animation features (like scrolls and fillable text fields).

Allow user input strings to be typed and reused in subsequents steps.
An input element should add a "input value n°1" entry to a list of global text values, and then those values can be used as text content for any text label in the subsequent steps.
