Following is a typical jquery script that can be used in a grails application. The property 'editable=true' make any of the field in grid as editable.

Often it is required to provide a drop down list for certain fields. To make any field as a combobox or a drop-down list make type as 'select' and provide 'editoptions'. eg: editoptions:{value:{1:'One',2:'Two'}}

The 'editoptions' list has to be hard coded or generated at the time of rendering. To dynamically generate the list using Ajax, we need to use the dataUrl as given below.


editoptions:{dataUrl:'${createLink(controller:"expenseType",action:"listAsSelect")}'}}


Controller action:

    def listAsSelect={

      def lst = ExpenseType.findAllByExpenseFlag('Y')

      println (lst.size())


      StringBuffer buf = new StringBuffer("")

      lst.each{
        buf.append("")
        buf.append(it.name)
        buf.append("")

      }

      buf.append("")

      render buf.toString()
      
    }
