Inputs
### Add adornments to input fields
The Vue Input components—TextBox, Numeric TextBox, Input Mask, and TextArea—support prefix and suffix adornments. These adornments enable the integration of icons, buttons, labels, or custom elements directly within the input boundaries. Users can attach events to adornments for actions, such as clearing content, toggling formats, or displaying validation indicators. This support is compatible with existing themes and floating labels, introducing no breaking changes. Prerequisites include setting up the standard component via the npm installation. Adornments enhance form usability in applications like user registration (e.g., country code prefixes in Input Mask), financial interfaces (e.g., currency symbols in Numeric TextBox), and content editors (e.g., character counters in TextArea). Positioning adapts to component-specific elements, such as spin buttons or resizable areas, ensuring consistent behavior across devices.
