Selectfilter in combination with images in column

eyk107

Hi everyone,

I've a a table with mixed filter fields (text box and select box as a dropdown). Everything is working fine except the column with icons in it. When I'm using a text box to filter that column I can filter it by the value but it didnt work with a select filter:

I would like to get the different possible titles as select values in the dropdown. The source code is in this jsfiddle:

Could anybody give a little advice?
Thank you very much.

Best regards
Eyk
