In Gridder, this option would only affect the profile page display, not the list tile since the labels are committed, displaying only the email address.
RE: edit template
The file you need to edit is:
The section of code to edit are between lines
To add the display of websites, use:
if ( $atts['show_links'] ) $entry->getLinkBlock( array( 'format' => $atts['link_format'], 'type' => $atts['link_types'] ) );
To add the display of addresses, use:
if ( $atts['show_addresses'] ) $entry->getAddressBlock( array( 'format' => $atts['addr_format'] , 'type' => $atts['address_types'] ) );
Remove the lines that yo do not wish to display.
Due to the way Gridder renders its panel, the default font size is set to
0. So, you might no be able to see addresses or links until you adjust the CSS to the desired font size. use your browser CSS inspector for the class selector you should target.
To ensure any changes you make are not lost when updating Gridder, please read these developer tutorials on how to make the changes update safe:
Hope this helps!
