Side-Menu Item Collapse

[ericbeland]

Thanks for the amazing theme--love it!

I'm wondering if there are any thoughts around collapsable menus?

Menu Collapse for Sidebar Menu

Some of the other blog themes offer sidebar menu collapsing. I'm wondering if:

1-Anyone else has an implementation they've used with jekyll-TeXT-theme?
2-If anyone knows of some code that could be "borrowed" to add this here?
3-If there are any pointers to (non-Jekyll) CSS that has a simple menu collapse to borrow
4-If I do this, would a PR be of-interest?

I realize that, at the end of the day, this is all just HTML, JS and CSS I can hack it up as I want,
but I'm never one to reinvent the wheel without looking for suggestions.

Thanks!
