dojox DropDownSelect fixed width

I wonder how to set fixed width for dojox.form.DropDownSelect (version 1.3开发者_如何学Go). I tried the following:

<select id="selectNode"  width="100px" dojoType="dojox.form.DropDownSelect" >
   <option value="opt">Some option</option>
</select>

<select id="selectNode"  style="width: 100px" dojoType="dojox.form.DropDownSelect" >

<select id="selectNode"  class="myclass" dojoType="dojox.form.DropDownSelect" > 
.myclass = { width: 100px }

You can't set width of DropDown Select less than width of biggest item. If you set width bigger - it would work OK. I propose to you if it possible use dijit.form.ComboBox instead of DropDownSelect . Width property for ComboBox will work in all cases. See example (last item - is ComboBox)
