I'm trying to create a dropdown of matrix field data using the search form. It's outputting the matrix data, but I can't seem to figure out how to remove duplicate content. Say I'm using the data "john doe" on multiple entries -- it's showing for every entry, not just once. Is there any way to fix this? Thanks in advance.
{exp:low_search:form query="{segment_3}"}
<label>Arranger:</label>
<select name="search:tags:arranger">
{exp:channel:entries channel="products" dynamic="no"}
{tags}<option value="{arranger}">{arranger}</option>{/tags}
{/exp:channel:entries}
</select>
<button type="submit">Search</button>
{/exp:low_search:form}
