Button showing up after checkbox selection

Button showing up after checkbox selection

  
Hi,

I am currently implementing task list where I added for each task a checkbox to allow the user to choose the ones to act upon. The selected tasks are saved in a task list variable.

I want to show a button immediately after selecting one task, the idea is to apply the same action to multiple actions if more than one is selected. My question is how can I dynamically trigger the appearence of the button when checking one checkbox? 

I have tried creating an action (onChange) when the checkbox is selected, but had no success at all.

Thanks.

Hi Inês,
 
you are thinking right. In your "on change" screen action you must set an ajax refresh action that will refresh the button you want. In your button visible option you must set a condition identical to this one "CheckBox Variable Name"=True" and then when you check your checkbox the button will appear, if you uncheck the button will disappear.

I hope it helps.

Best regards,
