问题 I've got a list of links on a main page that can be filtered via different checkboxes.

This works in all other places except for CheckBoxPreference.

问题 It is obviously very simple question but I have never done such thing before. My designer want some thing like this for check boxes (it is on left side. Checked ones are grey and other white). 回答1: One idea is to use a span with background-image (empty box), hide a related checkbox, and assign a clickhandler to the the span (onclick: change checked attribute of the related hidden checkbox, change background image of the span accordingly).

问题 So, i have this problem with some checkboxes. First of all let me tell you about the "project" itself. It's a webform, the user must complete it and check some checkboxes and radio buttons depending on what he would like to purchase.
