hi corncomps, here the instructions to do that if you are using Bliss template:
1.- Open templates/bliss/live_main.tpl
2.- Find this code :
<table width="90%" border="0" cellspacing="1" cellpadding="2" class="border">
<tr>
<td class="dark"><div align="center">{if $retry == 'true'}<b>{$lang.retry_select_department}</b>{else}{$lang.select_department}{/if}</div></td>
</tr>
{section name=i loop=$avaliable}
{if $avaliable[i].status == 'true'}
<tr class="online">
<td><div align="left"><input type="radio" name="departmentid" value="{$avaliable[i].id}"{if $departmentid == $avaliable[i].id} checked="checked"{/if} /> {$avaliable[i].name} - Online</div></td>
</tr>
{else}
<tr class="offline">
<td><div align="left"><input type="radio" name="departmentid" value="{$avaliable[i].id}" disabled="disabled" /> {$avaliable[i].name} - Offline</div></td>
</tr>
{/if}
{/section}
</table>
3.- Replace with this code:
<table width="90%" border="0" cellspacing="1" cellpadding="2" class="border">
<tr>
<td class="dark"><div align="center">{if $retry == 'true'}<b>{$lang.retry_select_department}</b>{else}{$lang.select_department}{/if}</div></td>
</tr>
<tr><td>
<select size="1" name="departmentid">
{section name=i loop=$avaliable}
{if $avaliable[i].status == 'true'}
<option value="{$avaliable[i].id}"{if $departmentid == $avaliable[i].id} selected{/if} /> {$avaliable[i].name} - Online</option>
{else}
{/if}
{/section}
</select>
</td></tr>
</table>
And it's done, I hope this helps
