# updownselect

Please make sure you have read the Tag Syntax document and understand how tag attribute syntax works.

> NOTE: that the `listkey` and `listvalue` attribute will default to `key` and `value` respectively only when the `list` attribute is evaluated to a Map or its descendant. Everything else will result in `listkey` and `listvalue` to be null and not used.

Create a Select component with buttons to move the elements in the select component up and down. When the containing form is submitted, its elements will be submitted in the order they are arranged (top to bottom).
