ext applying inline styles...that i don't want

[bcamp1973]

ext is applying inline styles to a combo box. i'm trying to position it, but the inline styles of course override anything i do...here's my code...

function customerSelect(){

    var customerStore = new Ext.data.JsonStore({
        url : '../shared/data/json_customers.php'
        ,root : 'customers'
        ,totalProperty : 'totalCount'
        ,id : 'id'
        ,fields : ['name']
    });
    
    var customerSwitch = new Ext.form.ComboBox({
        store : customerStore
        ,renderTo : 'customerSwitch'
        ,displayField : 'name'
        ,valueField : 'id'
        ,typeAhead : true
        ,mode : 'local'
        ,width : 130
        ,triggerAction : 'all'
        ,emptyText : '[selected customer]'
        ,selectOnFocus : true
    })
    
    customerStore.load();
} 

...and it's applied here...

<ul>
   ...
   <li id="customerSwitch"></li>
   ...
</ul> 

...and it's adding this...

<ul>
   ...
   <li id="customerSwitch" >
      <div id="ext-gen409" class="x-form-field-wrap" style="width: 249px; left: 439px; top: 216px;"> // <-- ???
         <input id="ext-comp-1034" class="x-form-text x-form-field x-form-empty-field" type="text" name="ext-comp-1034" autocomplete="off" size="24" style="top: auto; left: auto; width: 224px;"/>
         <img id="ext-gen410" class="x-form-trigger x-form-arrow-trigger" src="../ext-2.0.1/resources/images/default/s.gif"/>
      </div>
</li>
   ...
</ul>
