In Uranium, we can group interactions in two ways: an ur-set (which stands for "Uranium Set") or an ur-id (which stands for "Uranium ID"). An ur-set is defined when the whole interaction is wrapped in a
<div> (or other tag) with the attribute
An ur-id is defined when every component of a single interaction is given a unique ur-id attribute. For example, giving each component of an interaction the attribute
data-ur-id="unique_id". This is an alternative way to group a ur-set of HTML elements that may not be convenient to place together in the structure of your HTML document.
It's generally a better practice to use
data-ur-set to group interactions structurally as well as functionally. This allows for cleaner, well-structured, and more obviously hierarchical HTML. However, it isn't possible in all cases to wrap every interaction in an element with this attribute. It's in these instances we use
data-ur-id attributes. They are functionally the same — as seen below.
<div data-ur-toggler-component="button" data-ur-id="MyIDAccordion"> This toggler uses ur-ids </div> <ul data-ur-toggler-component="content" data-ur-id="MyIDAccordion"> <li>Thom</li> <li>Jonny</li> <li>Ed</li> <li>Colin</li> </ul>
<div data-ur-set="toggler"> <div data-ur-toggler-component="button"> This toggler uses an ur-set </div> <ul data-ur-toggler-component="content"> <li>Mission</li> <li>Guerrero</li> <li>Valencia</li> <li>Dolores</li> </ul> </div>
When the page is first loaded, Uranium automatically creates a unique ur-id for every ur-set element it finds on a page. These are numerical values with a "ur" prefix, starting with one, and incrementing by one for each ur-set encountered.
(Note: For that reason, we recommend that if you are creating an ur-id of your own, you use letters rather than numbers, to avoid conflicts with the automatically generated ur-id values.)
Uranium then searches through the HTML document for the special data attributes we use to add functionality to HTML elements. Once it sees an attribute that begins with data-ur, it looks for groups of components. The ur-set allows it to determine what interaction we're defining.
This is explained visually in the flowchart below.
