Personally, I'm having trouble with a side menu of you, I managed to style it but missing the small details that I need your help. I send the picture attached I have two problems, follow:
1) How can I make the initial state of the menu is closed (hide) the arrows to the left?
2) Where marked in red when the text breaks the line he gives a very large and still come to the right.
I'm waiting for you, Thank you!
