Solution: Open Dialog on Tooltip Click

Hello,

This requires you’ve got the tooltip+dialog setup;
https://wordpress.org/support/topic/popup-tooltip/

Once that’s in place if you want the tooltip to open the dialog then edit the imagemapper_script.js adding to the $(this).mapster({ options;

onShowToolTip: function(e) {
    e.toolTip.click(function(){
		OpenImgmapDialog(e.key, $('map[name="' + $(map).attr('usemap').substr(1) + '"]').get(0));
		$(map).mapster('tooltip', false);
    });
},

Bonus is to add cursor: pointer to the tooltip so looks like a link;
.imagemapper-tooltip:hover { cursor: pointer; }

Hope that helps someone,
Cheers
