@jom whats the benefit?

[jom]

I wanted to be able to override the locked in caret and instead use something like fa-angle-down (from FontAwesome). Caret is too small for what I'm using this for.

I was just going to put in an attribute for the CSS class itself, but wanted to be consistent with the rest of the extension.

You mean something like this i class="fa fa-home">

[jom]

Yes, although the fa-home icon probably isn't what I would choose for a drop down menu. Which is why I added the property iconOptions to be able to customize this tag. Not sure what else needs to be discussed; pretty minor change. I just don't think it should be locked into caret. I have it default to that if no class is specified.

Maybe instead of iconOptions attribute it should be a special part of options like we do on other widget -i.e. Nav

Vote for options name. iconOptions is not generic name. What if i do not have icons there?

@creocoder can you work on a pull request? It seems current one is kinda old one.

[creocoder]

@samdark Will do.
