Wow, so you want a WordPress tag cloud in a FM solution basically. No idea how but I wanted to subscribe, I can't wait to hear Phil's ideas on this one, interesting.
is that what those things are called? hahaha, i couldn't figure it out. thanks!
One idea I have is to use a loop to copy and paste from all the ::tags field into one field. And just try to apply random font sizes afterwards.
Substitute ( List ( RelatedTable::Tags ) ; [ ¶ ; " " ] ; [ "," ; " " ] )
Will turn carriage returns (added by the list function) and commas into a single space character. That will allow you to combine the text of multiple related records--which I think is what you asked for here.
To get different font sizes for different items, the simplest, is to select the text in its tag field and apply a font size to it. If that won't work, you may need to define a calculation field that applies a text size to the tags field and replace the reference in the above calculation with a reference to this calculation field.
