ADF Basics : Implementing auto suggest behavior in ADF Faces lov (list of values)


Auto Suggest behavior is best understand by Google Instant, as in google when we type something and it starts showing suggestion instantly.

 This effect can be implemented in ADF using autoSuggestBehaviour
To use the auto-suggest functionality in a declarative way you need to define a model-driven list of values on your model project, which will be the base for the suggestedItems list. Select the Department Name attribute from the Department VO and create a List of Values. here i am using HR schema and predefined table Department to implement this

  • Create a Fusion Web Application
  • Now create EO and VO of Department table.(Business Components)


  • Now create List of values(LOVs)on DepartmentName



  • Create page in ViewController and drag the DepartmentName on page as ADF Lov ChoiceList or Lov Input

  • Now go to Component Palette and select Auto Suggest Behaviour and drop it inside DepartmentName Lov


  • Now select af:autoSuggestBehavior from Page structure and go to PropertyInspector and Open Expression Builder at SuggestedItems and select from bindings #{bindings.DepartmentName.suggestedItems} if you are using different tables and Lov select according to that



  • Now run your page and enjoy autosuggest behavior (ADF Instant) 
Cheers :-) Happy Learning

      Hi Latha

      When you drop an attribute as input lov then it's binding is created in page def and that binding appears in expression builder
      Which Jdev version you are using ?
      Go to binding section of page and check that input lov binding is created or not

      Thank You Ashish. I rectified the error. I am using this in ADF Table so instead of bindings i should choose row.bindings.

      First drop autoSuggestBehavior tag in lov then check it in bindings and expand associated lov binding , there you will see suggestedItems

      You need to refer lov model from outside of table , add lov binding to page and then use #{bindings.PenTypVal.suggesteditems} referring that LOV Binding

    Hi Ashish,

    There is an attribute to set maxSuggestedItems where we can set max No of suggested Items

    Is there a way to set min suggested items to some 20 if available

      No there is no way and why you need that Chaitanya ?
      If there is any record in list then it'll appear on page , No need to set minimum number

    Hi Aashish,

    My scenario is such that I have viewobject MaterVO and I have another VO lovVO from which LOV values are fetched. lovVO returns two values id and name. Now if i create LOV on one attribute of MasterVO let suppose as as name and store id in backend db o form submit but display name from lovVO then auto suggest behaviour is working if search for ids and not for names.
