I want to code to move the button to another space. I can not find where is that function
We don't support moving elements yet, but you can usually get around that by showing/hiding elements.
Can you explain a bit what are you trying to achieve?
Adding to what Tomer said, wix being a WYSIWYG tool, we do not allow moving elements. However, there are a few ways to still make a design with moving parts.
Your can design two buttons in two different locations, Anne make one of them hidden. When you want to "move the button", hide one and show the other.
