I would have suggested it myself except that I almost never use switch/case. I have in fact become quite adept at using showif/hideif in innovative ways to achieve the same results, and because of this I seldom use if/then/else as well ... :)By the way, I would like to provide one important word of warning here:The way switch/case works in webdna is to display ALL the matching cases, not just the first matching case. This is NOT the way switch/case works in other popular software products!In the other software I've used, only the FIRST matching case is shown.I was very disappointed to learn that I could not use webdna's switch/case to select only the first match from a long list of options. And although I'm sure one could be added, there is *still* no preference (not even an optional "match=3Dfirst" parameter) that would make it display only the first match.This is the biggest reason why I never use switch/case myself.:(-- Kenneth Grome-------------------------------------------------------------This message is sent to you because you are subscribed to the mailing list
