Hiding/Displaying Forms (Checkbox forms) — javascript

[xandersky]

I have a plain-text representation of board of size X x Y using an underlaying 2D array presented on the screen. Each cell has either 1 or 0 as a value and there are preset array configurations that have users can choose that display on the board.I want the users to be able to choose their own custom board configurations (i.e. picking which cells should be 1, while unchecked ones are 0). To do this, I simply set up a 16 x 16 table of checkbox inputs. At the bottom of this is a submit button where they can click to draw the board once they've chosen their configuration.\[code\]<table> <tr> <td><input type="checkbox"></td> <td><input type="checkbox"></td> ... </tr> <tr> <td><input type="checkbox"></td> <td><input type="checkbox"></td> ... </tr> ...</table>\[/code\]My question: How can I hide/display the checkboxes when necessary? I only want to display the checkbox inputs when a user specifically clicks that they want to create a custom layout. Once they select the boxes and press submit, I'll process the data, but I then also want to hide the checkboxes. Is this possible? Thanks!
