I’m a bit confused as the title says drop-down and you’re also talking about a window.
Are you having trouble with the DHTML dropdown text, or are you expecting to see a popup?
Problem solved… I think.
I had created a DHTML drop-down text box with conditional tags. In order to do this I copied an existing drop down and amended the text inside it.
My problem was that whilst the old drop down displayed correctly when you click the “+” sign, the new drop down does not do so.
I tried deleting it and re-creating it from scratch but with no success.
However, when you copy the DHTML link from the master page it works fine.
So, following a hunch I re-applied the Master style sheet and CSS to the topic concerned and everything now seems to work.
My only concern is that without testing every link I don’t know which topics require the master sheet to be re-applied so I may just do all of them
