Interested in a hands-on experience of how this works? Check out the Multi-style labels widget in my sidebar. There are three icons one for each style - just click any icon and you will see the labels in that style. I have set zoom style as the default style.
- Icon for list style
- Icon for menu style
- Icon for zoom style
Excited about this? Try it in your blog. First, goto Template->Page elements tab and remove your label element IF you have one. Then, goto Edit HTML tab (no need to expand widgets) and identify the start of the sidebar section by looking for this line.
<b:section class='sidebar' id='sidebar' preferred='yes'>
Insert the code from here after that line (right-click, save it and copy/paste). Once you have inserted, you could goto Page elements tab and move this new Labels element. If you don't want the combo, you could use the zoom style alone by inserting the widget code from here.
