Which tag is used with both radio buttons and picklists to create the selectable values?

Using this tag you can used with both radio buttons and picklists to create the selectable values <apex:selectOption> 

Thanks

Hi,

You need to use apex:selectoption for your requirement.

<apex:page controller="chooseColor">
<apex:form>
<apex:selectList id="chooseColor" value="{!string}" size="1">
<apex:selectOption itemValue="red" itemLabel="Red"/>
<apex:selectOption itemValue="white" itemLabel="White"/>
<apex:selectOption itemValue="blue" itemLabel="Blue"/>
</apex:selectList>
</apex:form>
</apex:page>

controller -

public class chooseColor {
String s = 'blue';

public String getString() {
return s;
}

public void setString(String s) {
this.s = s;
}
}

Hope this helps.
