# Data Attributes

## Data- attribute reference

The jQuery Mobile framework uses HTML5 `data-` attributes to allow for markup-based initialization and configuration of widgets. These attributes are completely optional; calling plugins manually and passing options directly is also supported. To avoid naming conflicts with other plugins or frameworks that also use `data-` attributes, set a custom namespace by modifying the `ns` global option.

## Button

Links with `data-role="button"`. Input-based buttons and button elements are auto-enhanced, no `data-role` required

data-corners | true | false

data-iconpos | left | right | top | bottom | notext
data-iconshadow | true | false
data-inline | true | false
data-shadow | true | false
