I found an example on the tiddlywiki website, but a bit more advanced to be used for assigning different tags to a particular tiddler depending on the choice you make in the drop down
but what i need is much simpler , and not sure if its the same thing ,so is it even possible?
Note that the macro (i.e. \define … \end) needs to be at the top of your tiddler.
The macro is triggered inside the select widget in the “actions” attribute.
I’m assuming that you only wanted ONE of the selections to trigger an action. So the list widget in the macro checks to see if you’ve selected “vendor” as the status.
