Thank you @Mark. It seems the {{{filter...}}} has a lot of potential to
create conditional statements. The actual use case was based on the user
interaction a set of classes shall be applied to few html tags. I used the
dictionary tiddler, but for small use cases I like your approach.
@Tones, thank you. I like these kinds of threads where the scripting
features of TW are discussed and I always learn new things.
Thank you Jed, Mat, Mark, and Tones.
Best wishes
Mohammad
