units such as rem,em don't work in easyui?
<input class="easyui-textbox" style="width: 180px;" data-options="label:'abc'"> works!
but
<input class="easyui-textbox" style="width: 10rem;" data-options="label:'abc'"> is invalid.

Use this code instead.

Code:

<span style="display:inline-block;width:20rem;>
	<input class="easyui-textbox" style="width:100%">
</span>
