You can override this to create customized buttons of various kinds. The string `%choice%` will be changed to the corresponding element of the `choices` array. You may also specify an array of strings, if you need different HTML to render for each button. If you do specify an array, the `choices` array and this array must have the same length. The HTML from position 0 in the `button_html` array will be used to create the button for element 0 in the `choices` array, and so on.
