How to set a custom icon for IconBox or IconList ?
And how to make an iconbox title clickable to another page on the site ?
1) That’s currently not possible. You can only use the icons which are bundled with the theme.
2) We’ll add this feature in the next update. For now download http://www.mediafire.com/?66koyk7s6u9z3ol and http://www.mediafire.com/?zr84b75q6y80k7u and place them into the wp-contentthemesenfoldconfig-templatebuilderavia-shortcodes folder.
