I have primefaces steps using tag <p:steps>
like below :
<p:steps activeIndex="3" styleClass="custom" readonly="false" style="padding: 20px;">
<p:menuitem value="step 1." actionListener="#{masterController.menuSales(preferencesController)}" update="mainPanel"/>
<p:menuitem value="step 2." actionListener="#{masterController.menuCustomer(preferencesController)}" update="mainPanel"/>
<p:menuitem value="step 3." actionListener="#{masterController.menuItem(preferencesController)}" update="mainPanel"/>
<p:menuitem value="step 4"/>
</p:steps>
And the result is like this :
I can click step 1 but not step 3 and 4. How can I enable click for all steps?
Wow, that's a nice question!
I've tried many things with the current API to accomplish it, but seems like it's not possible with our current options.
To solve this I wrote a custom renderer for the Steps component:
Most of the code below is the same from the PrimeFaces's GitHub. I just changed a few things to solve this specific problem.

ResponseWriter writer = context.getResponseWriter();
String itemClass;
if (steps.isReadonly()) {
itemClass = (index == activeIndex) ? Steps.ACTIVE_ITEM_CLASS : Steps.INACTIVE_ITEM_CLASS;
} else {
if (index == activeIndex) {
itemClass = Steps.ACTIVE_ITEM_CLASS;
}
else {
itemClass = Steps.VISITED_ITEM_CLASS;
}
}
String containerStyle = item.getContainerStyle();
String containerStyleClass = item.getContainerStyleClass();
if (containerStyleClass != null) {
itemClass = itemClass + " " + containerStyleClass;
}
//header container
writer.startElement("li", null);
writer.writeAttribute("class", itemClass, null);
writer.writeAttribute("role", "tab", null);
if (containerStyle != null) {
writer.writeAttribute("style", containerStyle, null);

encodeMenuItem(context, steps, item, activeIndex, index);
writer.endElement("li");
}
@Override

ResponseWriter writer = context.getResponseWriter();
String title = menuitem.getTitle();
String style = menuitem.getStyle();
String styleClass = this.getLinkStyleClass(menuitem);
writer.startElement("a", null);
writer.writeAttribute("tabindex", "-1", null);

writer.writeAttribute("id", menuitem.getClientId(), null);

writer.writeAttribute("href", targetURL, null);
if (menuitem.getTarget() != null) {
writer.writeAttribute("target", menuitem.getTarget(), null);
}
} //POST
else {
writer.writeAttribute("href", "#", null);
UIComponent form = ComponentTraversalUtils.closestForm(context, steps);
if (form == null) {
throw new FacesException("MenuItem must be inside a form element");
}
String command;
if (menuitem.isDynamic()) {
String menuClientId = steps.getClientId(context);
Map<String, List<String>> params = menuitem.getParams();
if (params == null) {
params = new LinkedHashMap<String, List<String>>();
}
List<String> idParams = new ArrayList<String>();
idParams.add(menuitem.getId());
params.put(menuClientId + "_menuid", idParams);

}
onclick = (onclick == null) ? command : onclick + ";" + command;
}
if (onclick != null) {
writer.writeAttribute("onclick", onclick, null);
}
}
writer.startElement("span", steps);
writer.writeAttribute("class", Steps.STEP_NUMBER_CLASS, null);
writer.writeText((index + 1), null);
writer.endElement("span");
Object value = menuitem.getValue();
if (value != null) {
writer.startElement("span", steps);
writer.writeAttribute("class", Steps.STEP_TITLE_CLASS, null);
writer.writeText(value, null);
writer.endElement("span");
}
writer.endElement("a");
}
Then, register this new renderer in your faces-config.xml
file:
<render-kit>
<renderer>
<component-family>org.primefaces.component</component-family>
<renderer-type>org.primefaces.component.StepsRenderer</renderer-type>
<renderer-class>YOUR_PACKAGE.CustomStepsRenderer</renderer-class>
</renderer>
</render-kit>
Don't forget to change YOUR_PACKAGE to your CustomStepsRenderer package location.
After that, just build/re-deploy your application and everything should work fine:
