Tag suggestionbox

This element adds "on-keypress" suggestions capabilites to any input text component (like <h:inputText>). It creates a pop-up window for a input field component pointed to by the "for" attribute. For an ordinary request, render a hidden HTML <div> element and the necessary JavaScript code. When input to the target field exceeds the "minChars" property (default is 1), perform an AJAX request with the value current entered. If the AJAX request is detected and the request parameters map contains the client ID of this component, call a method defined by suggestionAction, and use it to return a value as data for render table, same as <h:dataTable>. In this case, the component then works the same as an ordinary dataTable. The rendered table is inserted in the pop-up area and is used for suggestion prompts for input element. If a user clicks on such a table row, its text (or value defined by fetchValue) is inserted as the value of the input field.
