问题
I have a simple vertical one-dimensional menu. Menu items are not fix, they change dynamically according to data received from the server. (So I cannot write fix code for them.)
In css I declared selected MenuItem to be bold. My wish is simply to make the selected MenuItem remain bold after selection. But when I click it, it loses focus and the first MenuItem becomes bold.
How could that be fixed?
