Hi,
1/ how to make the link to be opened in a new window tab?
Please edit this file : ../modules/mod_floating_buttons/tmpl/default.php
at lines 26 you will see this
code:"icon":"child_item_icon; ?>"
change that to
code:"icon":"child_item_icon; ?>", "target":"_blank"
2/ is it possible to have a message tip that disappears after few seconds next to the floating button?
If you know javascript you can do that via jQuery. Basically you just need to add something like this in proper condition :
jQuery(document).ready(function() {
jQuery('.jfab_tooltip').delay(5000).fadeOut('slow');
});
