Multiple select with checkbox from dropdown in PrimeFaces

问题

In PrimeFaces, can we choose multiple elements from drop down list with the help of checkbox? If my drop down is showing 5 elements, can I choose more than 1 element from the list?

I know in primeFaces we have <p:selectOneMenu> which will allow me to choose one element, but do we have something like <p:selectMultipleMenu>?

I was trying to find it out but not able to find something. Can you please let me know whether this is possible or not?

回答1:

There is <p:selectCheckboxMenu /> and it seems to provide what you need as you can see in showcase on: PrimeFacesShowCase-SelectCheckboxMenu

回答2:

It looks like the SelectManyMenu is exactly what you need.

EDIT: miroslav_mijajlovic's answer may be better because you wanted a drop down.
