There was a question - "How can i make drop down fields open on click and not on hover"
https://forums.mb-themes.com/veronika-osclass-responsive-theme/how-can-i-make-drop-down-fields-open-on-click-and-not-on-hover/msg10744/#msg10744 - and the answer was given but I have another not big  issue with this.

 
It remains open even if I make any other actions. For example if click on the page or open another custom field (you can see it beneath). One custom field cover another and do not close. I want it close not just by click on a field but also by click on the page or any else.

So, who knows what to do there? Please help

You need to put into jQuery code to hide box when click on outside.
