Trigger to open a list

[Dete]

Ok. Now I have made the menu for it and used item properties and mouse double right click as the trigger - the trigger is showing as - ##R, but I am getting other problem, that this trigger is disrupting my normal rightclicks in all applications, that when rightclick mouse once it shows the qmmenu (on just one right click and not two rightclicks). and then when I dont choose any menu item in the menu appeared, and again rightclick (just 1 rightclick), then it shows the normal rightclick of the application window currentused.
In item properties, as double right click, all the options are checked - eat, double, released.

Also, can I change the menu appearance, as fontsize, fontname, and add transparency to it ? thanks
