Help! highlighted text boxes

[Annieo38]

Hi,

Sorry I can't give much info. I'm trying to format a document and want to insert highlighted grey boxes which I've seen in previous documents. They usually say "please enter text here" and when you click on it the writing disappears and the grey highlighted area disappears.

Thanks,

Annie
