創建一個按鈕，你可以單擊它，然后添加一個新按鈕。

你必須創建一個動態UI，使用maxscript UI元素，將卷展欄構建為字符串，然后評估該字符串并打開新的卷展欄以更新你的UI；使用RolloutCreator（請參閱幫助文件）幫助您構建卷展欄，并打開新的卷展欄以更新您的UI，看下面的示例：
 

global roll_buttons
global build_rolloutfn addAnotherButton = (roll_buttons_count += 1counter = roll_buttons_count as stringroll_buttons += "button btn_" + counter + " \"Button " + counter + "\"
"
)
roll_header = "rollout roll_test \"test\" (button btn_test \"點擊我\"on btn_test pressed do (destroyDialog roll_testaddAnotherButton()createDialog (buildRollout()))
"
roll_footer = "
