oculto/visible

[txarly]

Se puede hacer con capas:

Aqui debajo te pongo un ejemplo, es algo básico para que lo pruebes y si puedes adaptarlo a lo que necesitas.

Código:

<SCRIPT LANGUAGE="JavaScript">
<!--
function TabClick(srcElement) {
	if (srcElement.id == "form1a" || srcElement.id == "form3b") {
			div1.style.visibility = "visible";
			div1.style.display = "block";
			div2.style.visibility = "visible";
			div2.style.display = "block";
			div3.style.visibility = "hidden";
			div3.style.display = "none";
	} else if (srcElement.id == "form2a") {
			div1.style.visibility = "visible";
			div1.style.display = "block";
			div2.style.visibility = "visible";
			div2.style.display = "block";
			div3.style.visibility = "visible";
			div3.style.display = "block";
	} else if (srcElement.id == "form3a") {
			div1.style.visibility = "visible";
			div1.style.display = "block";
			div2.style.visibility = "visible";
			div2.style.display = "block";
			div3.style.visibility = "visible";
			div3.style.display = "block";
	} else if (srcElement.id == "form2b") {
			div1.style.visibility = "visible";
			div1.style.display = "block";
			div2.style.visibility = "hidden";
			div2.style.display = "none";
			div3.style.visibility = "hidden";
			div3.style.display = "none";
	} 
}
//-->
</SCRIPT>


<DIV id=div1 style="VISIBILITY: visible; DISPLAY: block"><!-- form1 -->
<FORM METHOD=POST ACTION="">
	FORMULARIO 1<BR>
	<input type="button" id=form1a onclick="TabClick(this);" value="OK1">&nbsp;
	<input type="button" id=form1b onclick="TabClick(this);" value="FIN1">
</FORM>
</DIV>

<DIV id=div2 style="VISIBILITY: hidden; DISPLAY: none"><!-- form2 -->
<FORM METHOD=POST ACTION="">
	FORMULARIO 2<BR>
	<input type="button" id=form2a onclick="TabClick(this);" value="OK2">&nbsp;
	<input type="button" id=form2b onclick="TabClick(this);" value="FIN2">
</FORM>
</DIV>

<DIV id=div3 style="VISIBILITY: hidden; DISPLAY: none"><!-- form3 -->
<FORM METHOD=POST ACTION="">
	FORMULARIO 3<BR>
	<input type="button" id=form3a onclick="TabClick(this);" value="OK3">&nbsp;

</DIV>
