You can also use Radio buttons for the Input Option Values.
To explain the example above, (with the || and == symbols). It’s actually really simple. The minimum version would just have the pipes. Say your three banners are red, blue, and green.
In the Input Option Values field:
name_of_red_chunk||name_of_blue_chunk||name_of_green_chunk
In this version, the manager/editor would see the three choices and whichever one is selected will show up in the TV content tag [*tv_name*]. This won’t work for what you want because it will just print the name of the selected chunk rather than showing the content of that chunk. To make it output the the chunk, you need to add {{ ... }} to make it a chunk tag.
{{name_of_red_chunk}}||{{name_of_blue_chunk}}||{{name_of_green_chunk}}
Now the contents of the selected chunk will appear wherever you put a [*tv_name*] tag.
The extended version adds double equals signs and a value after each choice. The first part (before the ==) is what appears when someone edits a document with the TV, the part after the == shows up in the TV content tag [*tv_name*].
red=={{name_of_red_chunk}}||blue=={{name_of_blue_chunk}}||green=={{name_of_green_chunk}}
You could use the simple version, or you could use the fancy version -- your choice. The only difference would be how things look when editing a document with the TV.
Hope this helps.
