Drop-Down in Struts 2

I have a map with key-value pairs. I want to display the key on a drop-down and value to be sent to server for identifying what is selected.

I am using Struts2. I tried putting the Map in <s:select> tags list, however it shows the values in the dropdown.

Solution

  • Use listKey and listValue attributes of <s:select> tag to get properties from list of objects.

    In order to swap keys and values in map put value in listKey and key in listValue.

    <s:select list="someMap" listKey="value" listValue="key"/>
