javascript - Why does the WeChat applet picker become two lines?

Question

The picker selector is used in the WeChat applet. If the picker is written in a view, the picker style will be displayed in two lines.

<view class="pickergroup">
<picker bindchange="ChooseWolfNumber" value="{{wolfIndex}}" range="{{area_wolf}}">
Number of wolves: {{area_wolf[wolfIndex]}}
</picker>>
</view>

Why do multiple pickers affect each other? For example, if 3 is selected in the first selector, will the remaining selectors start from the 3rd one by default?
