Hide Default Submit Button in Drag and Drop Quiz

[alfredmack]

Hi,

I have a drag and drop slide with 3 drop targets and 1 drag object with one attempt set. Now I want to hide a submit button until a drag object is dropped in any of the three drop targets to avoid empty submission, unfortunately default submit button has no id which I can use to hide. I have tried to refer similar issues in the forum and I saw another idea of making another button and put on top, when I tried this I came to notice that the button is still clickable even when is behind another button. Any help please..

Stacking interactive objects is NEVER a good idea, although some experts claim it works. It used to be possible for SWF output but is to be avoided for HTML5 output.

The Submit button is an embedded object, like all the quiz buttons. You can drag it out to the scratch area, you can activate the Auto Submit (works only for correct answers). Moreover you can use the Object actions.  That may be a solution for  you to avoid empty submit. Create a counter variable which you increments which each object action. Add a second decision to that action, which checks the value of the counter and shows a previously hidden text (or state of a multistate object) to warn if the counter variable is still equal to zero.

Thanks for your quick response, I'm expecting my users to pick wrong/correct answer for this case I think auto submit won't be a solution to my problem.

What about my other proposal?

[alfredmack]

Please correct me if I'm wrong, In this case the object action(s) will be executed when the item is dropped in "drop target". For this case user will still be able to click submit button since object action can't hide it or disable it to be clicked.

You are correct, answered too quickly.  Checking the counter variable needs to happen with the Failure action, but the problem is that this Failure action is in reality a last attempt action.

Is this a scored D&D slide,  or a Knowledge Check slide? A KC slide can be reset easily, a scored slide not that easy.

[alfredmack]

It is scored D&D slide.

That is complicating. Try this (didn't check it myself):

1. Make the default Submit button 'invicible'. It is mostly a Transparent button (of you can change to that type). Set both Alpha and Stroke to 0.
2. Create a shape that looks exactly the same as the Submit button before making it invisible and locate it over the invisible Submit buttons. Make that shape invisible in Output.
3. Use the object actions to trigger the command 'Show shape' to make the shape visible. 
4. Although the Submit button is invisibe I suspect it will be activated when clicking the shape.... you have to double-check.

[alfredmack]

The button will still be clickable even after making it transparent. You won't see it since it is transparent but when you click where is located will trigger (submit)

[Lilybiri]

Sure, but the learner doesn't see where the button is at all. You can count on that.

Another workaroud is to drag the Submibutton out in the screatch area except a very small part. Use a motion path effect, which you'll have to define as custo meffet£. This will be more complicated because you'll have to avoid that it moves in more than once, you'll need a combined conditional action as object action, taking into account the counter variable I mentioned in my first answer.
