Button/Text Box visible upon the next Layer

The problem I have and I dont understand is:

• I make a Sprite (Layer 1)
• put some buttons and text-box on it (Layer1)
• than i change the position from another sprite (which is on Layer2) over the first Sprite

and however the text-boxes and Buttons are visible on the Sprite which is one Layer over their. :/

hope you understand my terrible english :D

sounds strange

a example

From the manual:

Form controls are actual HTML elements floating above the game canvas in the HTML page. Therefore, nothing can be displayed on top of a form control, apart from other form controls.

So set them just invisible as soon as you move something over them.

To avoid bugs insert into your on form actions a condition: is visible

Thx for both helpfull answers ;)
