I would like when the menu is presented the "Option 1" starts selected, something like an html Selected

<p:selectManyMenu id="basic" value="#{selectManyView.selectedOptions}">
    <f:selectItem itemLabel="Option 1" itemValue="1" />
    <f:selectItem itemLabel="Option 2" itemValue="2" />
    <f:selectItem itemLabel="Option 3" itemValue="3" />
</p:selectManyMenu>

In your Java code you probably have something like this:

public class SelectManyView{
    private List<String> selectedOptions;

    public List<String> getSelectedOptions() {
        return selectedOptions;
    }
}

In your class constructor, start the list with the values you want to be already selected. Something like this:

public class SelectManyView{
    private List<String> selectedOptions;

    public SelectManyView(){
       this.selectedOptions = new ArrayList<String>();
       this.selectedOptions.add("1"); // é o campo itemValue do Option 1
    }

    public List<String> getSelectedOptions() {
        return selectedOptions;
    }
}

  • It did not work, it returns the items in the list normally but is not selected

Have you tried using the attribute noSelectionOption?

Example:

<p:selectManyMenu id="basic" value="#{selectManyView.selectedOptions}">
    <f:selectItem itemLabel="Option 1" itemValue="1" noSelectionOption ="true"/>
    <f:selectItem itemLabel="Option 2" itemValue="2" />
    <f:selectItem itemLabel="Option 3" itemValue="3" />
</p:selectManyMenu>

You add the attribute noSelectionOption in the item you want to leave selected. Remembering that it is necessary to pass the value of true for the attribute.
