Validation
Name	Type	Default	Description
`OverrideFieldValidation`	bool?	null	If a field already has a validation, override it with MudForm.Validation.
`Validation`	object	null	A default validation func or a validation attribute to use for form controls that don't have one. Supported types are: Func<T, bool> ... will output the standard error message "Invalid" if false Func<T, string> ... outputs the result as error message, no error if null Func<T, IEnumerable< string >> ... outputs all the returned error messages, no error if empty Func<object, string, IEnumerable< string >> input Form.Model, Full Path of Member ... outputs all the returned error messages, no error if empty Func<T, Task< bool >> ... will output the standard error message "Invalid" if false Func<T, Task< string >> ... outputs the result as error message, no error if null Func<T, Task<IEnumerable< string >>> ... outputs all the returned error messages, no error if empty Func<object, string, Task<IEnumerable< string >>> input Form.Model, Full Path of Member ... outputs all the returned error messages, no error if empty System.ComponentModel.DataAnnotations.ValidationAttribute instances
Validated data
`ChildContent`	RenderFragment	null	Child content of component.
`Model`	object	null	Specifies the top-level model object for the form. Used with Fluent Validation
Validation result
`Errors`	string[]		Validation error messages.
`IsValid`	bool	True	Validation status. True if the form is valid and without errors. This parameter is two-way bindable.
Behavior
`IsTouched`	bool	False	True if any field of the field was touched. This parameter is readonly.
`SuppressImplicitSubmission`	bool	True	When true, will not cause a page refresh on Enter if any input has focus. https://www.w3.org/TR/2018/SPSD-html5-20180327/forms.html#implicit-submission Usually this is not wanted, as it can cause a page refresh in the middle of editing a form. When the form is in a dialog this will cause the dialog to close. So by default we suppress it.
`SuppressRenderingOnValidation`	bool	False	When true, the form will not re-render its child contents on validation updates (i.e. when IsValid changes). This is an optimization which can be necessary especially for larger forms on older devices.
`ValidationDelay`	int	300	Validation debounce delay in milliseconds. This can help improve rendering performance of forms with real-time validation of inputs i.e. when textfields have Immediate="true".
Common
`Class`	string	null	User class names, separated by space.
`Style`	string	null	User styles, applied on top of the component's own classes and styles.
`Tag`	object	null	Use Tag to attach any user data object to the component for your convenience.
`UserAttributes`	Dictionary<string, object>		UserAttributes carries all attributes you add to the component that don't match any of its parameters. They will be splatted onto the underlying HTML tag.
