Parameters:

Name	Type	Description	Default
value	dynamic(Any)	The value represented by this control.	None
password	bool	If True, the text is obscured, and all characters are displayed as asterisks ('*'). This can be useful for sensitive information such as passwords.	False
label	str	The label associated with the input field. This provides context to the user and improves accessibility.	None
multiline	bool	If True, the input is rendered as a multi-line text area The default behavior is a single-line input.	False
lines_shown	int	The number of lines displayed in the input control when multiline is True.	5
type	str	The type of input element, as per HTML input types. This property enforces specific input formats where applicable. Supported values include "text", "tel", "email", "url", etc.	text
action_on_blur	bool	If True, the on_action callback is triggered when the input control looses keyboard focus (e.g., when the user presses the Tab key). When this happens, the key name for the event (set in the args property of the payload parameter to the callback function) is set to "Tab".	False
change_delay	int	The minimum interval (in milliseconds) between two consecutive calls to the on_change callback. The default value is defined at the application configuration level by the change_delay configuration option. if None, the delay is set to 300 ms. If set to -1, the callback is triggered only when the user presses the Enter key.	App config
on_action	Union[str, Callable]	A function or the name of a function that is triggered when a specific key is pressed. The callback function is invoked with the following parameters: state (State): the state instance. id (str): the identifier of the control if it has one. payload (dict): the callback details This dictionary has the following keys: action: the name of the action that triggered this callback. args (list): The key name pressed. The variable name. The current value of the variable.	None
action_keys	str	A semicolon-separated list of keys that can trigger the on_action callback. Authorized values are Enter, Escape, and function keys F1 to F12.	Enter
width	Union[str, int]	The width of the element, in CSS units.	None
on_change	Union[str, Callable]	A function or the name of a function that is triggered when the value changes. The callback function receives the following parameters: state (State): the state instance. var_name (str): the bound variable name. value (Any): the updated value.	None
propagate	bool	Determines whether the control's value is automatically reflected in the bound application variable. The default value is defined at the application configuration level by the propagate configuration option. If True, any change to the control's value is immediately reflected in the variable.	App config
active	dynamic(bool)	Indicates if this element is active. If False, the element is disabled, and user interaction is not allowed.	True
id	str	The identifier assigned to the rendered HTML component. This can be used in callbacks or to target the element for styling.	None
properties	dict[str, Any]	A dictionary of additional properties that can be set to the element.	None
class_name	dynamic(str)	A space-separated list of CSS class names to be applied to the generated HTML element. These classes are added to the default taipy-input class.	None
