Your information goes here. This is a good control for unobtrusively hiding text that you want your website visitors to have access to, based on demand. If they're not interested, they don't click to expose the info or they can hide it, if it's already exposed.
This feature is useful where you would normally have 'additional info' available, for a particular product's specifications or more details on a subject of interest. Having the ability to hide and expose information is a very handy feature. The Panel control is somewhat similar to the Accordion component, in that respect (collapses and expands).
