我有一个多功能组合盒，里面有元素。目前，组合框和项目的宽度不相等:
我想让两个元素的宽度相同，如下所示:
我已经尝试过了
<MultiComboBox width="auto">
<items>
<core:Item key="ac" text="ac"/>
</items>
</MultiComboBox>
还有这个
<MultiComboBox width="100%">
<items>
<core:Item key="ac" text="ac"/>
</items>
</MultiComboBox>
还有这个
<MultiComboBox>
<items width="100%">
<core:Item key="ac" text="ac"/>
</items>
</MultiComboBox>
但是，没有任何效果。有人能给我建议吗？
最佳答案
其实你可以做到这一点。这就是窍门:MultiComboBox 有一个隐藏的聚合picker，您可以通过函数getPicker 获取它。它返回一个 sap.m.Popover 实例，该实例又具有 2 个属性(contentWidth 和 contentMinWidth)，甚至还有 beforeOpen。技巧是在 beforeOpen 事件中设置 contentWidth 或 contentMinWidth。

// The trick - setting of contentWidth or contentMinWidth of Combobox Dropdown list
var oPicker = oSelect.getPicker();

oPicker.attachBeforeOpen(function() {

oPicker.setContentMinWidth(oSelect.getWidth());
});
} else {
console.error("Picker is empty");
}
oSelect.placeAt("content");
