Create a WordPress menu (up to three levels) with the WP appearances built-in menu builder and convert it to a nice responsive dropdown using template tags.
Choose your colors, and whether you want a hover or click (click will be permanent on responsive break due to mobile devices’ use of hover as a “pre-click”).

Sinking Dropdowns WordPress

Convert default WordPress menu to a responsive hover/click dropdown menu.

JQuery Hover Footnotes lets you add footnotes with qualifiers of you’re choosing, then dynamically displays them on hover-over. So you can easily add footnotes to a post by wrapping them in qualifiers, then they will dynamically display in a jQuery hover popup when the user mouses-over the footnote link. There is also a settings page where you can change options like the footnote formatting.
Features
-Numbers, Words, or ANSI characters can be used as footnote reference marks 
-Footnotes can be superscript, subscript, or normal text 
-Footnotes can be placed in page footer or hidden 
-Popup/Hover footnote can be turned on and off.
Usage
To anchor the footnote reference mark/number, use {{FOOTNOTE_NUMBER}}. Then just embrace the actual footnote text with double brackets [[FOOTNOTE_NUMBER]] Footnote text [[FOOTNOTE_NUMBER]]. The footnote text can be placed either inline or at the bottom of the post, the plugin will find them and auto place them in the footer area.
So this is what you would write in the post window…
This is my post and I want to add a footnote{{1}} in the text. By default it will appear as a superscript.
[[1]] My Footnote. [[1]]
