Sorry for bumping a really old thread but…
I would also like to see some examples of styling the embedded list of topics. Mine looks like the phone version on desktop
how do I make it be full width?
Sorry for newbie question
EDIT:
To answer my own question
TL:DR
the following had to be placed in the page the list is embedded in
<style>
d-topics-list iframe{
width: 100%!important;
}
</style>
looks great on mobile as well!!
I figured this out from this thread
