/* Dynamic search result display */

/*
The following two functions require that the form being submitted adheres to the
following characteristics

	- id: combo
	- three input types in the following order:
		- input to set the parent search
		- input to set the child search 
		- input to set the 'display search' property

Example for struts form:	

<html:form action="/actionName" styleId="combo">
	<html:hidden property="chosenBranche" name="awoGWForm"/>
	<html:hidden property="chosenSubBranche" name="awoGWForm"/>
	<html:hidden property="displaySearch" name="awoGWForm"/>
	<input type="hidden" name="language" value="<%= language %>">
	<input type="hidden" name="country" value="<%= country %>">
</html:form>
