#link_to_visibility_toggle(id, options = {}) ⇒ Object

Creates a javascript-based link that toggles the visibility of some element on the page. By default, it toggles the visibility of the sibling after the one it’s nested in. You may pass custom javascript logic in options to change that, though. For example, you could say :of => ‘$(“my_div_id”)’. You may also flag whether the other element is visible by default or not, and the initial text will adjust accordingly.
