The owner of plugin replied to me, he said that is normal. Some browser could have this delay.
So i have to change the plugin.
Question
i'm using this very nice plugin on my website for mobile device and i notified that when click to open menu, it takes 1 sec delay.
Also in the demo plugin page mmenu.frebsite.nl (visit from mobile) you should see the same behaviour.
In the code: jquery.mmenu.js ln 74 there is a sort of note about this delay.
Could it be fixed and have a fluid open/close menu? (close action is perfect)
thx for any response
