Change data entry state or trigger so it only appears when filled?

Hello,

I have this question regarding the data entry box, I'm not sure if it is possible using Storyline, but would appreciate any alternative solutions in that case.

I'm building a slide with multiple layers. Each layer will have multiple textboxes that trigger the appearance of words on the base slide when clicked.

I would like the user to have the option of filling in their own idea if the options do not suit. For this, I thought of using data entry, but as I discovered, I cannot change the state, as I have done for the other triggers.

My problem arises when I would like the data entry box to remain in the sentence if it has been filled in.

I tried using another layer, however, this involves duplicating the slide... and it disappears when another layer is clicked. It's getting complicated!

Here's what I have so far, see the Behaviour and Content layers.

As I said, if it's not possible the way I have tried it, please let me know if you think of any alternatives.

Thanks!

Valerie
