You’d add the HTML that you need inside the formatText() function. You’d probably want to build the HTML and test it so it all looks good and is the right size; then just concatenate a string inside the formatText() function. If you wanted to return a DIV tag, you’d do something like this:
var myHtml = “
What the formatText function does is to set the HTML of the little "tab" under each panel of the AnythingSlider. For each panel, the AnythingSlider calls this function to get the HTML, so it serves as a template for the tabs. The HTML can contain anything you need, but it should be kept small enough to go with the design. The function has the index of that panel, as the argument "index" so you can reference that in your code as I’ve done in the example above.
