Transfer

Customizable

You can customize list titles, button texts, render function for data items, checking status texts in list footer and list footer contents.

:::demo Use titles, button-texts, render-content and format to respectively customize list titles, button texts, render function for data items, checking status texts in list header. Plus, you can also use scoped slot to customize data items. For list footer contents, two named slots are provided: left-footer and right-footer. Plus, if you want some items initially checked, you can use left-default-checked and right-default-checked. Finally, this example demonstrate the change event. Note that this demo can't run in jsfiddle because it doesn't support JSX syntax. In a real project, render-content will work if relevant dependencies are correctly configured.

Prop aliases

By default, Transfer looks for key, label and disabled in a data item. If your data items have different key names, you can use the props attribute to define aliases.

:::demo The data items in this example do not have keys or labels, instead they have values and descs. So you need to set aliases for key and label.
