# List Filter Help. ???

 * Hi Roland,
    I hope all is well with you. I’m using the following shortcode at
   [https://www.sohophoto.com/exhibition-list/](https://www.sohophoto.com/exhibition-list/)
 * [pdb_list template=multisearch search_fields=”artist_last, opening_date” orderby
   =opening_date,id order=desc,desc fields=”artist_fullname, show_title_with_link,
   opening_date, artsylink” filter=”category=Exhibition|category=Group Show” ]
 * Currently the “category” field is a Radio Button Element.  I would like to change
   that to a Multi-Select Checkbox, so that more than one category can be selected
   for a particular record.
 * When I make that change in the DB, the shortcode filter fails and the page returns
   ZERO results.  When I revert the field to a Radio Button, it works.  Which is
   the current state.
 * How can I fix that, so that I can have a field with two or more selections that
   still filter on the selected categories for a particular list?  
 * Please Let me know … 
    THANKS!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Flist-filter-help%2F%3Foutput_format%3Dmd&locale=en_US)

 * You cannot use “=” with a multi-select type. The field data is represented by
   an array because there can be multiple selections, so you need to do a substring
   match. Use a filter like this instead:
 * `filter=”category~Exhibition|category~Group Show”`

 * As always — THANK YOU for the rapid reply. I understand and will give it a spin…
   and revert only when I get jammed up again.
    David.
