How to use Checkboxes June 4, 2017 11:16AM UTC
Klaus-Dieter Grueninger 2 Posts	Hi there, I am currently working on an optics project and I wonder how I can use Checkboxes to determine the visibility on an element. I assume it is quite simple, but I have no clue how to do it. Can you name any EJSS in Javascript where this has been done so I can see how to implement it? Thanks Klaus-Dieter Login to reply

Yes it is easy.

Set the drawing element visible option to a variable say showWhatever to make objects appear and disappear when the Boolean showWhatever is control in the checkbox.
