使用Orbeon Builder根据下拉值隐藏和显示其他控件

Question

如何使用Orbeon构建器创建表单，用户可以在其中从下拉列表中选择值，并基于选择可以看到其他控件已呈现（可能是隐藏/显示）。

Answer 1

1. First, give a meaningful name to that dropdown field; say gender .
2. Click on the Edit Choices icon for that field, just below the Control Details icon, and in the dialog assign meaningful values to each choice. Those are the values you'll refer to in step 3.
3. Finally, in the Control Details for the other field, under the Formulas tab, if you want that field to only be shown if the value of the gender field is female , enter the XPath expression $gender = 'female' .
