Index of Velo Examples

I have looked for a tab element for pages and found here the example of show-hide, which might provide a similar function. But our interest is to have different Google Event Calendar apps for each “tab” or for the list of selections to show-hide. It isn’t clear to me how (or even if) different instances of the app can be placed in the hide-show code (instead of different images or text literals). What kind of elements can be shown-hid?

Thanks for any observations about this.
