I have a message function in my app, where messages are send by pressing a ‘big’ Send button. I prefer however that a user just presses the Enter button on it’s keyboard. I;ve seen an example where there is a button (with width and height of just 1x px), which is located on the right bottom of the multiline input of the message. But I don’t understand why this setup works?
As you said, you can create a button (linked to a workflow that create the message) near the input and group those two elements in a group. Then, we you press enter, it automatically launch the button’s workflow - aka creating a message thing.
You can put the button really small or invisible, if you want to suggest the user he just have to pushed enter…
Hope it helps
