wpcrm_system_menu_icon
The wpcrm_system_menu_icon filter controls the icon that is shown in the left side menu in your WordPress admin dashboard area.
By default, this filter returns the Dashicons helper class ‘dashicons-id’.>
You can modify the output with one of the following:
- The URL to the icon to be used for this menu.
- Pass a base64-encoded SVG using a data URI, which will be colored to match the color scheme. This should begin with ‘data:image/svg+xml;base64,’.
- Pass the name of a Dashicons helper class to use a font icon, e.g. ‘dashicons-chart-pie’.
- Pass ‘none’ to leave div.wp-menu-image empty so an icon can be added via CSS.
