The `<tc:in/>` tag create a classic inputfield.

In most cases, a label should be placed in front of every inputfield. Use the attribute `label`.

    <tc:in label="Input" value="Some Text"/>

The following inputfield should be selected after reloading the page. Use the `focus` attribute.

    <tc:in label="Input (focus)" focus="true" value="Some Text"/>

An inputfield can be set as required with the `required` attribute. Such an inputfield must contain a value, otherwise a submit is not possible. Leave the field blank and press 'submit' to see the errormessage.

    <tc:in label="Input (required)" required="true"/>

To create an inputfield for passwords, set the `password` attribute to 'true'. It will hide the text as shown in the following example.

    <tc:in label="Password" password="true" value="password"/>

A `placeholder` attribute can be used for explaining a user the meaning of a field.

The text of the placeholder is only shown if the value is an empty string.

    <tc:in label="Placeholder" placeholder="Grey Text"/>

The outputfield in this example, displays the given value on the server. With `<f:ajax render="outputAjax" listener="\#{inController.update}"/>`, the outputfield will be rerendered, after the value has been changed. This is because `outputAjax` is the id of the `<tc:out/>` tag. and the default event for `<tc:in/>` is `change`. Additional, the `listener` attribute is set. The given method is called after the inputfield loose focus.
