Over the past eighteen months, numerous navigation helpers have been released. Fixed, floating, slide-out, drop-down, pop-up; the variations have been so endless that yet another of these menus seems like pouring water onto a hot stone – it's just going to vaporise along with the rest…
Weavium recently released just such a menu stack, but this one takes the idea a whole step further – A multi-level floating menu that is either permanently visible, or appears just when you need it!

I have to admit that when I first looked at the Dive demo page, my initial thought was "another one? Why?" Upon taking a closer look, however, I have to admit that Dive is different.

A menu button with an icon of your choice in any, or all four corners of your page that is either static and permanently visible, or appears when it is scrolled to and can disappear again when a scroll marker has been reached.
Each Dive child stack can have multiple levels, so if for instance you have "Support" in the first level, it can open up to offer "FAQs; Forum; Contact" when clicked, then whisk you away to the appropriate page on the second or third click.
The only disappointing aspect about Dive (as with other recent Weavium Stacks) is that, while you can have your visitors zip to another page or to a page anchor on the same page, I was unable to persuade it to open a lightbox.
I've mentioned this to the Weavium team and, with any luck, this may be remedied in the near future.

Colours & Fonts

Each Dive Item Child stack has the option to add Sub Items and options to customise the colours. There are also settings for choosing Icons and Icon colours, but I was unable to find a way to activate Icons. Probably an oversize on my behalf.

Dive is one of those navigation helpers that is a little different to the rest. The options for multiple levels are unique as are the show and hide options that can be activated for multiple page sections. This is certainly a useful stack!
