Example of how to create a form, a dropdown list with options, display them and then retrieve information from the dropdown list:

PHP Code:

            //create a form: Form(form_name, page_to_redirect, method)
            $formExample = new Form("exampleform", "page_to_send_to_here", "post");
            
            //create a dropdown list object: DropdownList(name)
             $exampleDropdown = new DropdownList("myList");
              
              //add options to dropdown list: Option(option_name_displayed, option_value)
                 $exampleDropdown->add(new Option("Option1", "option1")); 
                 $exampleDropdown->add(new Option("Option2", "option2")); 
                 
                 //add dropdown list to form
                 $formExample->add($exampleDropdown);
                 //add button to form
                 $formExample->add(new Button("Click Me", "submit", "submit"));
                 //add form to document to display it
                 $document->add($formExample);   
                 
                 //after clicking button to submit form
                 if($mysidia->input->post("submit")){
                       //retrieve option selected in the dropdown list, by the dropdown list name
                       $chosenOption = $mysidia->input->post("myList");
                       $document->add(new Comment("I chose this: {$chosenOption}"));
                 }
