Installe de uitkit switcher. you can see 1 example on the page. at the right of the picture i placed a bit of tetx but when i give a name in the header the text is gone so you can see in this example.
Can you tell me what is going wrong?

Hover your mouse over the white area and you'll see the text appear. You need to adjust the text color, because white on white is invisible.
