Question

It is necessary to close the Superfly Menu when submitting the form in the mobile version.
I can't find the menu close event in the documentation.
Manually removing styles is somehow not correct and there are too many of them.
I wanted to make a click on the menu closing cross through jquery, but for this you need to install the plugin for click () to work on mobile devices.
