I am following the example to make my own custom form design: http://www.web2py.com/book/default/chapter/
{{=form.custom.begin}} Image name: <div>{{=form.custom.widget.name}}</div> Image file: <div>{{=form.custom.widget.file}}</div> Click here to upload: {{=form.custom.submit}} {{=form.custom.end}} Generated HTML is: Click here to submit: <input type="submit" value="Submit" /> I want to add my own tag data-theme="e" so the final HTML to be: Click here to submit: <input data-theme="e" type="submit" value="Submit" /> Or simply to change the background color to make the Submit button better visible. How to do that?
