The sample code below would create a form with a select box of all collections, a query input box and a submission button all in one row.
<s1ws:form> <table cellspacing="0" cellpadding="3" border="0"> <tr class="navBar"> <td class="navBar"><s1ws:collElem type=”select”/></td> <td class="navBar"> <s1ws:querybox size="30"/> <s1ws:submitButton class="navBar" style="padding: 0px; margin: 0px; width: 50px"/> </td> </tr> </table> </s1ws:form>
