Question

The right column works perfectly, when I try to do the same with the left one it acts as if it was disabled.

I hope somebody can spot what’s wrong here

Answer 1

If you set the z-index on #leftblockreal, it should be selectable:

#leftblockreal {
    left: 0;
    position: fixed;
    top: 0;
    z-index: 1;
}
