I use the following code to filter entries by category:
<select name="selcat" onchange="location=document.catmenu.selcat.options[document.catmenu.selcat.selectedIndex].value;">
<option value="">--Select Category--</option>
<option value="{path="/{my_weblog}}">ALL</option>
{exp:weblog:categories weblog="{my_weblog}" style="linear" dynamic="off"}
<option value="{path={my_weblog}}">{category_name}</option>
{/exp:weblog:categories}
</select>It works like a champ but it doesn’t continue to show the option that I selected. Is there a quick and dirty fix for this?
