Examples of org.itsnat.comp.label.ItsNatHTMLLabel

org.itsnat.comp.label.ItsNatHTMLLabel
Is the interface of HTML <label> based components.
ItsNat provides a default implementation of this interface.

This component may be useful to forms with non-fixed labels (e.g. internationalized forms).

By default the component has the default renderer but no editor.

In place edition is not recommended with this kind of component because when a <label> is clicked the default behavior (specified by HTML) is to click the associated form control.
