[Javascript] Specific areas for the action of the mouse

[javascript@xxxxxxxxxx (Pietro Carubbi)]

Hallo,

I have a page where a customized menu is displayed on right click. This menu
can be closed by a 'close' button within it.

After this right menu appears, I want that the user can only:

- select an item from the list;

- close the menu by clicking the button;

- utilize the scrollbar which controls a text-field in the page.

Any other action of the mouse should be prevented while the right menu is
still opened.


Is this possible? How?

Bye,

Pietro
