Thanks Rodrigo …
I did not explain the first point well.
I do not want to hide the 3 buttons, what I want is that the drop-down menu (mobile version) be hidden, retract when you click on one of these 3 buttons. (with the other buttons if it is hidden, the problem is those 3).
Hello Rodrigo, I again …
I have a problem with the hamburger menu, it is not hidden with the 3 buttons that I indicate in the image, it is necessary to click again on the icon to close the menu.
