//方案预设: 多方案选择组件
|
//控制显隐： 1.未开启时全不显示
|
// 2.开启后显示已解锁 + 未解锁 3+0
|
//a. 按元宝解锁的为逐一开启，默认开启x个，第x+1个显示条件需要【流派预设】功能开启, 可解锁后逐一保留一个锁住的（直到全开启）；
|
//b. 按功能条件开启的，如果默认只开其一个方案的情况不显示，达到下一个方案的条件满足后全显示；默认大于1个的情况直接全显示
|
// 3.当小于4个的时候，没有下拉显示，如果可以超过4个的显示下拉
|
// 4.当大于4个的时候，选择超过方案4时，第四个显示为选中的方案; 否则重开的时候默认显示1-4 不记录历史点击
|
// 5.名字展开分两种情况，外层功能默认不展开，点击后切换展开状态；流派预设界面里只有展开状态不可收缩
