从UI添加（命名）或删除一组UI元素（&N）

Question

我正在maya中制作一个UI，在那里我想创建一个带有一组textFieldButtonGrp的下拉选项卡（提示命名选项卡），或者在我按add'+'或remove'-'按钮时删除它。你知道吗

UI代码（带一个选项卡）：

import maya.cmds as cmds
import pymel.core as pm
import maya.cmds as cmds
import maya.OpenMaya as om
import math

from functools import partial

        self.gtF1 = tsL1

                                    buttonLabel='Elbow IK',bc = 'Create_Selection_Chains.select_joints_ikpv(left_arm_select)' )
        self.gtF2 = tsL2

        self.cmds.separator(h=5)
        self.cmds.button(label= 'Remove' + self.name, command = 'Remove()', width=100)
        self.cmds.separator(h=5)

我的问题是我不确定如何将新的选项卡内容添加到UI中

有人能给我指出正确的方向吗？你知道吗
